Sync.com is my personal favorite cloud storage and is what I recommend the most to my friends. It offers zero-knowledge encryption, secure collaboration via Microsoft Office and unlimited cloud storage space on its business plans. Though its free plan isn’t anything to write home about, its paid plans are very cheap, especially considering the value they offer. What Is Cloud Storage & How Does It Work? Cloud storage is a type of software that lets you upload your digital files to a remote online server, enabling you to keep a backup version of files that you can access from anywhere. Providers typically offer hot storage for frequently accessed files and cold storage for archival data, with the latter being more cost-effective but having slower retrieval times. As a fundamental component of cloud computing, cloud storage allows businesses and individuals to store, access and manage data through internet-connected servers rather than local hardware. Keeping your files in the cloud also opens up paths for remote file sharing and online collaboration. Cloud storage is great for uploading and sharing photos, and some cloud services even let you play media files, like music and video. To learn more, read our guide on how cloud storage works . Benefits of Cloud Storage There are pros and cons with cloud storage , but overall, the benefits outweigh the risks. These are the key benefits of cloud storage: Remote file access: Storing your files in the cloud makes them accessible to any of your devices with an internet connection. File backup: You can back up your files by uploading them to the cloud. File sharing: You can easily share any file once it’s in the cloud. File syncing: Cloud storage apps synchronize your files across devices. File recovery: These features allow you to restore accidentally deleted files or previous versions, providing a safety net against user error or corrupted documents. Selective syncing: This disables syncing for selected files to save cloud storage space. Cloud security and encryption: Cloud storage services can encrypt your data on their servers so it isn’t accessible to anyone. Zero-knowledge encryption: Some cloud companies offer zero-knowledge (or client-side) encryption, which can prevent the cloud company itself from accessing your files. Mobile photo uploads: Cloud storage apps for Android and iOS can automatically upload all the photos you take with your phone. Versioning: Most cloud storage options keep multiple previous versions of your files, including deleted files. Block-level sync: Some top providers use block-level sync technology, transferring only the modified portions of files rather than entire files, resulting in faster sync times. Compliance: Many providers offer GDPR compliance to ensure your data is handled according to strict EU privacy regulations, protecting user rights regarding personal information.

The 14 Best Cloud Storage Comparison Though you might think that Google Drive, Microsoft OneDrive and Dropbox are the only cloud storage providers, there’s actually a diverse ecosystem of vendors, each offering a unique solution. The table below compares 14 of these services, including their features and pricing. Detailed Cloud Storage Speed Comparison We ran our speed tests by uploading and downloading a 5GB test folder over a 1 Gbps connection that had been throttled to 100 Mbps (for both uploads and downloads) to ensure stable speeds. We ran the tests twice for each service and averaged the results. We provide a more detailed breakdown, along with notes on our experience speed testing each service, in the provider segments. Most services performed about the same in the download test. The results of our upload test were more varied, with a wider margin between the top and bottom results. IDrive tops our charts for both uploads and downloads, with the former being particularly impressive. Our testing rig is located in Ireland, which means that services with European data centers will have an advantage due to proximity. Here are our test results. Average Upload Time by Provider Minutes per 5GB Folder Average Download Time by Provider Minutes per 5GB Folder 1. Sync.com — Best Cloud Storage for Personal Use Great value for the money Zero-knowledge encryption Offers unlimited cloud storage Slower than competitors Free plan offers only 5GB Who Is Sync.com For? Security-minded users: Sync.com is the best encrypted cloud storage because it offers client-side encryption across your entire storage, as well as complying with strict privacy laws and regulations, such as HIPAA and PIPEDA. Businesses and power users: Sync.com offers some of the cheapest unlimited cloud storage plans, while also integrating with Microsoft Office for collaboration purposes. Lawyers and legal firms: Sync.com’s high security and HIPAA compliance mean that it’s deemed private enough to store even sensitive medical data. That is on top of its document editing capabilities via its Microsoft Office integration. Small business owners: Sync.com has some of the best cloud file sharing features, letting you set expiry dates and passwords, send upload requests for folders and monitor sharing link activity, making it perfect for sharing files with customers and contractors. What Does Sync.com Do? Sync.com is our favorite cloud storage service, offering a slew of security features, such as zero-knowledge encryption and hardened physical servers in Canada. Its Canadian servers also mean your privacy is protected by PIPEDA — a Canadian privacy law that protects private information online. Sync.com is also the best software for file sharing , letting you set passwords and expiry dates for sharing links, and disable or limit downloads. It even notifies you when a shared file is viewed or downloaded. This affordable cloud service enables file editing via Microsoft Office integration and is protected by client-side encryption for private cloud collaboration . The service now offers advanced team file-sharing controls, allowing administrators to enforce mandatory password protection and expiry dates for all shared content across their organization. This is particularly valuable for business users focused on data security. Sync.com Hands-On Testing For support, Sync.com offers desktop apps for Mac and Windows, plus mobile apps for iOS and Android. Linux support is still in the works. The desktop apps follow the sync folder model popularized by Dropbox, though you can’t sync other folders on your device. You get one folder that holds all of your cloud files, all of which are synced to the cloud. Mac users can now enjoy the improved CloudFiles functionality, providing better integration with the operating system and more reliable file syncing capabilities while maintaining the same level of security. Its mobile apps are similarly sparse, letting you access files remotely and automatically upload your photos and videos. The web app is cleanly designed and easy to use. Notes From the Lab: Sync.com Speed Test Results Unfortunately, Sync.com is also among the slower services we’ve tested. Speeds fluctuated wildly when uploading, though they stabilized when it got down to just a few very large files. Download speeds were more stable but still not impressive. Notably, the initial indexing stage took nearly a full minute, which added to the total time spent performing tasks. Notes From the Lab: Sync.com Security & Privacy Analysis Key Security & Privacy Features: Client-side encryption Two-factor authentication HIPAA compliance possible GDPR compliance (EU users) Canadian privacy laws (PIPEDA) Collaboration in zero-knowledge environment Duplicate files across servers for data loss protection Sync.com uses AES-256 encryption at rest. This cipher is uncrackable (in theory) and is the gold standard for encryption. Your data is also duplicated across multiple servers to protect it against earthquakes, floods, fires and other natural disasters. Sync.com complies with HIPAA, which means it’s secure enough to handle even sensitive medical data. Unlike many competitors, Sync.com maintains zero-knowledge encryption even when collaborating through Microsoft Office Online, ensuring your documents remain private while enabling real-time collaboration. Sync.com Pricing & Value Sync.com’s free tier offers just 5GB of storage, but its paid plans offer some of the best value on the market. Sync.com is among the cheapest cloud storage options, costing just $4.80 for 2TB of storage on the yearly plan. You can even get unlimited storage for per user per month with a three-user minimum.

Videographers and video editors: pCloud puts no limits on file sizes and has an advanced media player for high-quality cloud previews of videos. Paired with upload requests and editing permissions for folders, this makes it the best cloud storage for collaborative video work. Linux users: pCloud is one of the few cloud storage services with native Linux support, and offers a uniquely polished experience thanks to its sleek app design, fast speeds and responsive file syncing. Music lovers: pCloud offers the best music player of any cloud storage service, with support for FLAC files for enhanced audio quality, and automatically sorting your music by artist and album. What Does pCloud Do? pCloud is like a Swiss army knife of cloud storage features, particularly for entertainment. Its full-feature music player makes it our top music cloud storage service, and its Kodi integration lets you stream movies and videos stored in the cloud. pCloud also has no file size limits, making it the best cloud storage for video editing. Besides these features, pCloud offers cloud backup, giving you the option to upload files to the cloud at a set interval without syncing them. This is great for keeping an archive of files that you don’t need to access frequently. pCloud Hands-On Testing pCloud offers true cross-platform compatibility, with seamless file access and syncing across all your devices, such as Windows, Mac, iOS and Android. It even includes a native Linux client, making it the best cloud storage for Linux . The apps are logically designed with a clean and legible interface, though they won’t win any awards for their looks. You’ll sync files via the sync folder, and you can also choose to synchronize other folders on your device. If you need to save space, pCloud lets you mount a virtual drive, which allows you to access cloud files, edit them and then upload them back to the cloud, without having to keep them on your device. The drive works even on Mac devices, providing direct access through File Explorer or Finder without consuming local storage space. pCloud now provides a QR code during installation that streamlines the setup process, making it even easier to get started on macOS devices. Additionally, Android users can now easily drag and drop files between pCloud and other apps, streamlining workflows for mobile users who work across multiple applications. There’s also a dedicated “upload folder” option in the “floating action button” menu, providing a more convenient way to upload entire folders rather than selecting individual files. Notes From the Lab: pCloud Speed Test Result Once among the fastest cloud services we’ve tested, pCloud performed pretty poorly in our recent upload speed tests, though its download speeds were among the fastest. For overall performance, pCloud ranks in the middle of the pack, though we also have to note the very low impact it had on CPU load. Notes From the Lab: pCloud Security Analysis Key Security & Privacy Features: Swiss privacy laws Two-factor authentication GDPR compliance (EU users) Client-side encryption (single folder, not free) Additional password protection for Crypto files We consider pCloud to be a private cloud storage service, but there’s a catch: You need to pay extra to enable client-side encryption. This will drive up the cost if you need the added privacy. pCloud offers servers in the U.S. and the EU, letting you choose the location when creating your account. We strongly recommend going with the European data center for the data protection the EU’s GDPR affords. Furthermore, pCloud is based in Switzerland, which has some of the strictest privacy laws in the world. pCloud Pricing & Value We consider pCloud one of the best free cloud storage services, with 10GB of free space and nearly all premium features, apart from advanced sharing. Its paid plans are affordable , with the 2TB plan costing $8.33 per month on the two-year plan. It also offers lifetime plans for even greater savings. For quick file sharing without commitment, pCloud offers pCloud Transfer, letting you send files up to 5GB by simply entering your email address and the recipient’s — no account required. Check out our full pCloud review to find out more about the service. + FREE Encryption + FREE Encryption Price per user (minimum 3) Price per user (minimum 3) Encryption for pCloud Drive 3. Tresorit — Secure Storage for Businesses Zero-knowledge encryption for all files Excellent file sharing controls with access logs and permissions Sleek desktop and mobile apps Pricier than alternatives Free plan is weak with strict limits Who Is Tresorit For? Security-first professionals and teams: If you handle confidential files — whether in law, finance or HR — Tresorit’s zero-knowledge encryption and SwissSign eSignatures make it a secure choice for managing contracts, agreements, and sensitive data. Medical and legal service providers: Tresorit is HIPAA-compliant and offers enterprise-level access controls, making it ideal for healthcare professionals and legal teams that must adhere to strict data protection regulations. Remote teams needing secure collaboration: Businesses with distributed teams will benefit from Tresorit’s secure file sharing, encrypted email integrations, and admin-level activity logs — all of which help keep internal and external communication private. What Does Tresorit Do? Tresorit stands out as the ideal cloud storage for users who place privacy and security above everything else. It’s a great fit for businesses in finance, healthcare and legal sectors, thanks to features like HIPAA compliance, SwissSign digital signatures, and eSign integration. All files are secured with end-to-end, client-side encryption — even on the free plan. In addition to airtight privacy controls, Tresorit integrates with Gmail and Outlook to offer encrypted communication — something rarely seen in the cloud storage space. For professionals handling sensitive data, Tresorit provides the peace of mind that most other services simply can’t. Tresorit Hands-On Testing Tresorit’s interface is clean and intuitive, with a logical layout across desktop, web, and mobile. While it doesn’t support features like file previews or document editing (in favor of stronger privacy), managing and syncing files feels seamless. Installing plugins is simple, although the lack of Safari support limits some Mac users. Notes From the Lab: Tresorit Speed Test Results IDrive’s speeds used to be a sore spot in an otherwise excellent service, they have improved significantly in recent years. Nowadays, the service is the fastest for both uploads and downloads, hitting max speeds throughout our tests and snagging only a little on the largest files. CPU usage was mostly low, with some moderate spikes. Notes From the Lab: Tresorit Security Analysis Tresorit offers excellent security, including client-side zero-knowledge encryption, 2FA, ISO 27001 certification, and GDPR-compliance. File sharing is locked down with access controls, link expiration, and activity logs. Tresorit Pricing & Value Tresorit’s plans aren’t cheap — personal users pay a premium for privacy, while business users get scalable plans with advanced features. The Tresorit free plan includes minimal storage and file size limits, but paid options start with a 14-day trial (credit card required). However, annual billing provides a discount. To learn more about the service, read our Tresorit review or try it out yourself with the 14-day free trial.

Proton Drive — Privacy-Focused Cloud Storage With Real-Time Collaboration Client-side encryption Polished apps on all platforms Real-time document collaboration via Proton Docs Selective sync limited to non-default folders Free plan version history capped at seven days Who Is Proton Drive For? Privacy-minded users: Proton Drive offers client-side encryption across your entire storage, and its servers are based in Switzerland, home to some of the world’s strictest privacy laws . Users wanting a full privacy ecosystem: Proton Drive integrates seamlessly with Proton Mail and Proton Calendar, making it ideal for users who want an all-in-one encrypted suite. It’s the privacy alternative to Google Workspace or Microsoft 365. What Does Proton Drive Do? Proton Drive is a secure cloud storage service from the makers of Proton Mail. It offers client-side encryption by default, meaning not even Proton can access your files. In 2025, Proton introduced functional Docs and Sheets editors, enabling real-time collaboration similar to Google Docs with no noticeable delays. Proton Drive Hands-On Testing Proton Drive’s apps are surprisingly polished on all platforms. We particularly like its full desktop application and excellent mobile photo organization features, including an in-app option to disable battery saving for uninterrupted uploads. In our sync test, Proton Drive handled conflicts without creating duplicates, and it passed our stress test with flying colors; we uploaded files in alphabetical order with smooth folder scrolling and no hangs. Notes From the Lab: Proton Drive Speed Test Results Proton Drive delivered stable and fast speeds in our 2026 tests, averaging around 25MB/s with peaks of 33MB/s and low CPU usage. This is a massive improvement from our past testing experience, showing the service has matured significantly. Notes From the Lab: Proton Drive Security Analysis Key Security & Privacy Features: Link expiry dates Swiss jurisdiction Client-side encryption Password-protected sharing links Proton Drive has client-side encryption for your entire account. This level of encryption applies to all of Proton’s ecosystem. It uses AES 256-bit encryption to secure your data at rest and TLS/SSL to protect it in transit. With servers in Germany and Switzerland, Proton affirms its stance on placing your privacy first. Both of those countries have strong privacy laws, which protect your data stored there. Proton Drive Pricing & Value Proton Drive’s free plan offers a modest amount of storage but includes zero-knowledge encryption by default. Paid plans are affordable, starting at around $3.99 per month for 200GB . Read our full Proton Drive review for more. per user, minimum of 2 users 5. Internxt — Affordable Lifetime Cloud Storage Open-source apps Lifetime storage plans Slower download speeds No collaboration options Who Is Internxt For? Budget-conscious users: Internxt’s paid plans are extremely affordable, if you can settle for its basic cloud storage features and slow speeds. Small business owners: Internxt’s backup feature can help your business with disaster recovery, in the event something happens to your on-premises devices. Plus, its cheap prices and lifetime plans mean fewer costs for your business. Users needing future-proof security : As far as we know, Internxt is the first cloud service to offer post-quantum cryptography, in addition to client-side, end-to-end encryption. What Does Internxt Do? Internxt is another highly secure cloud provider that offers client-side encryption. Its apps are open-source, letting you inspect the code for flaws, vulnerabilities or backdoors (if you have the knowhow). In March 2025, Internxt expanded its features beyond storage and basic backup options. All personal plans now support additional security benefits, including antivirus, VPN and more. However, it still has limited collaboration options. The service has some of the lowest cloud storage prices out there, including some pretty cheap lifetime plans. Internxt Hands-On Testing Internxt has apps for all major operating systems, as well as a command-line interface and WebDAV support, enabling integration with third-party apps that rely on this standard. The desktop app uses a single sync folder, with no option for syncing other folders. You can mark files as online-only to save space — thankfully, this is the default setting. The mobile app lets you take photos, but it doesn’t support automatic photo upload. Notes From the Lab: Internxt Speed Test Results Internxt’s upload speeds have massively improved since the last time we reviewed it, thanks to recent changes in its storage architecture. Oddly, uploads went very fast almost until the end, when speeds dropped off precipitously. Downloads were much worse, though, at times coming to a complete stop before picking back up. CPU usage was very low. Notes From the Lab: Internxt Security & Privacy Analysis Internxt is highly secure, offering zero-knowledge security and open-source apps. Its servers are located in the EU, which means your data is protected by the GDPR — the gold standard of privacy laws. Plus, a third party has audited its software, which fortifies its commitment to user privacy. What’s more, Internxt is pioneering the implementation of post-quantum cryptography, which is designed to protect your data against future quantum computing attacks that could potentially break traditional encryption methods. Internxt Pricing & Value Internxt’s free plan is the smallest on this list, with only 1GB of storage afforded to non-paying users. However, Internxt’s lifetime plans are among the most affordable you’ll find, starting at 1TB for $300 . Read our full Internxt review for more details.

Icedrive Hands-On Testing Icedrive stands out from the crowd for its excellently designed and easy-to-use interface. It’s available on Windows, Mac and Linux, as well as mobile devices running Android and iOS. We don’t often comment on aesthetics, but Icedrive’s interface is a real head turner, with cool colors, sleek lines and clean fonts. Icedrive lets you use a classic sync folder, but it also gives you a few other options. You can choose between the sync folder, a virtual drive and a portable app that requires no installation and can sync any folder on your device. The virtual drive was previously available only on Windows, but it has recently been ported to Mac and Linux as well. The service has also improved its background synchronization capabilities with the IceMon service, which addresses various sync issues and ensures better compatibility with both 32-bit and 64-bit Windows systems. Notes From the Lab: Icedrive Speed Test Results Though the top performers in our tests are all big names with massive server networks, Icedrive managed to squeeze into the top three fastest cloud storage services . It posted the second fastest upload speeds and somewhat average downloads. CPU load was high initially but quickly tapered off, while RAM usage was relatively high for cloud storage. iOS users will appreciate the improved “save to Icedrive” experience, which now provides more detailed information and error messages while optimizing memory usage during file transfers. Notes From the Lab: Icedrive Security Analysis Key Security & Privacy Features: Two-factor authentication GDPR compliance (EU users) Less common Twofish encryption Client-side encryption (single folder, not free) Unlike most cloud services, Icedrive uses Twofish encryption. This cipher should be even harder to break than AES-256, though in practice both are practically impossible to crack without a supercomputer or a few million years to spare. Icedrive offers zero-knowledge encryption, but it covers only one folder and isn’t available on the free version. Icedrive Pricing & Value Icedrive offers some of the best cloud storage pricing . Its paid plans are affordable but have data caps for file transfers. Icedrive’s best deal is the 3TB plan, which costs $9.92 per month with an annual commitment. Icedrive also offers lifetime subscription, with the Lifetime Core plan offering 2TB of storage for a one-time payment of $389 . You can then expand this plan with Icedrive’s 1TB and 5TB Stacks. Free users get 10GB of storage and no zero-knowledge encryption. Read our Icedrive review for more.

IDrive — Best Cloud Backup Service Full mobile backup Lots of cheap storage space Cloud backup & storage combined Lacks features like advanced sharing & productivity options Who Is IDrive For? Users needing cloud backup: If you need cloud storage for quick access, but also want a place for archiving old files, IDrive is an excellent choice as it is primarily a cloud backup service. Videographers and video editors: IDrive’s cloud storage space doesn’t eat into its backup storage. This means you effectively get twice the storage space that you’re paying for, making it excellent for storing large video files. Businesses and power users: Besides offering large amounts of storage for cheap, backups are an excellent way to recover data, especially in the case of cyberattacks on your business. What Does IDrive Do? IDrive is a bit of a wildcard on this list. It’s not strictly a cloud storage solution; in fact, it’s primarily a backup provider, but it integrates cloud storage into its platform. IDrive’s cloud storage does not eat into your cloud backup space, so you effectively get twice the storage capacity when combining cloud storage and backup. Though IDrive’s cloud backup is among the most flexible and feature-rich, its cloud storage is scantily featured. There are some basic file-sharing options but not much else. IDrive Hands-On Testing You can install IDrive on all desktop and mobile platforms. However, by virtue of primarily being a cloud backup service, its interface is more complicated to set up and use. Mobile users get an extra app, called IDrive Photos, which uploads photos and videos. It used to offer unlimited photo storage, though that’s sadly no longer the case. IDrive’s desktop apps let you designate any folder as a sync folder, and selective sync helps you save cloud storage space. The mobile apps work differently than most cloud storage apps, as they let you back up your entire phone, not just photos and videos. Paired with IDrive Photos, this makes IDrive a great cloud storage option for mobile users . In addition, IDrive offers hybrid cloud storage capabilities, so you can keep copies of your data both in the cloud and on local devices for maximum redundancy and faster access to frequently used files. The service even supports backing up network-attached storage (NAS) devices, allowing you to include your local NAS drives in your backup strategy without additional complexity. IDrive also lets you connect to FTP servers, and it directly integrates with enterprise storage solutions like Amazon S3 or Microsoft Azure Blob Storage within the same management interface. Notes From the Lab: IDrive Speed Test Results Though IDrive’s speeds used to be a sore spot in an otherwise excellent service, they have improved significantly in recent years. Nowadays, the service is the fastest for both uploads and downloads, hitting max speeds throughout our tests and snagging only a little on the largest files. CPU usage was mostly low, with some moderate spikes. Notes From the Lab: IDrive Security Analysis Though IDrive offers private client-side encryption, you have to select this option when you create your account. Because this is easy to miss, we knocked a few points off its score. However, we still consider IDrive to be one of the most secure cloud services. IDrive also implements continuous data protection, automatically backing up files as they change without waiting for scheduled backup times, ensuring your most recent work is always protected. IDrive Pricing & Value As of January 2025, IDrive no longer offers a free plan. However, IDrive’s paid plans are dirt cheap, especially when you consider the combined storage available between storage and backup spaces. Its best deal is the 5TB plan, which costs $6.22 per month on a two-year plan. Read our IDrive review for more information. No credit card required. One user, multiple computers. Plans starting from 5TB up to 100TB. Big discount for first-time signup. 5 computers, 5 users. Starting at 5TB up to 500TB. Big discount for first-time signup. Monthly Plan storage starts at 1.25TB up to 50TB Unlimited users, multiple computers and servers. NAS devices. 250GB storage. Starting at 250GB up to 50TB. Large discount for first-time signup. 8. MEGA — Best Free Cloud Storage Ample free plan Encrypted sharing links Up to 16TB of storage for paid plans Expensive paid plans Might not be fully zero-knowledge Who Is MEGA For? Free users needing lots of storage: With 20GB of free storage, MEGA offers one of the largest free plans, expandable to 30GB for the first year. This makes it an excellent choice if you don’t want to pay for cloud storage. Power users needing large storage capacity: MEGA offers paid storage plans up to 20TB , which is more than enough for most individuals’ needs. Business plans go all the way up to 10PB, though at that point you’d be better off going with an unlimited storage provider. What Does MEGA Do? Much like Texas, everything’s bigger with MEGA. It gives you more free storage space than any other secure cloud service, and it offers high-capacity paid plans that go all the way up to 16TB for personal users or a whopping 10PB for businesses (that’s 10,000TB). Unfortunately, MEGA doesn’t offer much beyond a lot of storage space. Encrypted sharing links with password protection are a welcome addition to its sparse feature set. The only other feature beyond secure file sharing is its end-to-end encrypted chat client, though this isn’t something you really need in a cloud storage service. MEGA Hands-On Testing MEGA supports Windows, Mac and Linux computers, plus Android and iOS smartphones. The desktop app serves only to sync folders on your computer to the cloud, but it can seem a bit obtuse if you aren’t familiar with cloud storage. You’ll mostly interact with MEGA’s browser extension, which thankfully sports a much more straightforward design. Notes From the Lab: MEGA Speed Test Results If we had to describe MEGA’s speeds in one word, it would be “middling.” In our speed test results, MEGA ranked fifth for uploads and eighth for downloads, placing it squarely in the middle of our testing lineup. The lightweight desktop app barely impacted our CPU and RAM during the tests. Notes From the Lab: MEGA Security Analysis Key Security & Privacy Features: Open-source apps Client-side encryption Encrypted sharing links Two-factor authentication Password manager (paid users only) GDPR compliance (extends to all users) End-to-end encrypted text and video chat Though MEGA uses AES-128 encryption, there should be no practical difference between AES with 128-bit keys and AES with 256-bit keys. All encryption happens client-side, so the company can’t access your files. MEGA’s encrypted chat feature provides end-to-end encrypted text and video communication, securing your communications beyond just storage. However, a security flaw discovered in 2022 revealed that MEGA might be able to access user files, at least as long as the user has logged in 512 times. Though one aspect of this vulnerability was promptly patched, the flaw is with MEGA’s security architecture itself. Therefore, we can no longer confidently call it zero-knowledge. MEGA Pricing & Value As we said, MEGA offers more storage space than any other service on the cloud storage scene, going all the way up to 10PB. Its best deal is the much more reasonable 3TB plan, which costs $9.78 per month. In our opinion, MEGA’s cloud storage plans are overpriced, considering the scarcity of features and the flawed encryption. A free account with MEGA gets you 20GB of free storage, which is expandable to 30GB for the first year by completing simple tasks. You can get extra storage from referrals as well, though that’s also time-limited to one year. Read our full MEGA review for more. File transfer: 3TB (Monthly plan) 36TB (yearly plan) File transfer: 10TB (monthly plan), 120TB (yearly plan) File transfer: 20TB (monthly plan) 240TB (yearly plan) Price per user (minimum 3) 3TB Transfer quota 9. Koofr — Best for Multiple Cloud Storage Accounts Manage multiple clouds Microsoft Office integration Remote file access without syncing Who Is Koofr For? Users of multiple cloud services: Koofr’s unique selling point is that it integrates with other cloud storage services — namely Google Drive, OneDrive and Dropbox — and lets you manage files within those services. Privacy-minded users: Koofr is a European company and complies with GDPR, while also offering a client-side encrypted vault for your most sensitive files. What Does Koofr Do? Koofr is a zero-knowledge cloud service with quite a unique set of features. It integrates with Dropbox, Google Drive and OneDrive , letting you access and manage their storage from within the Koofr interface. You can even access files remotely via the mobile app without uploading anything to the cloud. Koofr comes with Microsoft Office integration for real-time collaboration on documents. It also comes with a rudimentary image editor that lets you resize, crop or apply filters to pictures. Koofr Hands-On Testing Koofr is a pleasure to use. Despite its unique features, its apps (available on all major operating systems) are well designed and easy to use. Plus, every feature comes with an explanation, so you’ll know exactly how to use it. The zero-knowledge vault comes as separate web and mobile apps, though, and they’re not as well designed as the main apps. Koofr creates a sync folder by default upon installing the app, but you can choose to sync any folder on your computer or even remove the default folder. You can also add a virtual drive to save space. All of this customization is nice to have, but it can easily get complicated and you could end up duplicating files. Thankfully, Koofr also comes with a duplicate file remover to fix this issue. Overall, Koofr’s ability to integrate with multiple cloud services makes it an excellent tool for implementing a multi-cloud strategy, where you can manage and access files across different providers from a single interface. Notes From the Lab: Koofr Speed Test Results Koofr’s speed performance has worsened slightly since we last tested it, now sitting firmly below the average for both uploads and downloads. In particular, the larger files seemed to cause uploads to stall quite heavily. Thankfully, CPU and RAM usage remained low throughout. Notes From the Lab: Koofr Security Analysis Key Security & Privacy Features: Uses only login cookies Two-factor authentication GDPR compliance (all users) Client-side encryption (single folder) Data duplicated across three servers Koofr’s main selling point is its privacy. Though it doesn’t cover your entire storage with client-side encryption, it does offer a protected vault. In addition, its servers are based in Germany, meaning your data is covered by the GDPR. Notably, Koofr’s website uses no third-party cookies, and the only first-party cookie it uses maintains logins. Koofr Pricing & Value Unfortunately, Koofr’s biggest flaw is its pricing. Its 10GB free plan is decent and its smaller plans are cheap, but its higher-capacity paid plans are harshly priced. Its 1TB plan costs $10 , more than most 2TB offerings. Read our full Koofr review to learn more about this quirky cloud storage service. *Prices in Euro *Prices in Euro *Prices in Euro *Prices in Euro *Prices in Euro *Prices in Euro *Prices in Euro *Prices in Euro *Prices in Euro *Prices in Euro 10. OneDrive — Integrated Cloud Storage for Windows Comes preinstalled with Windows Paid plans come with Microsoft Office Up to 1TB cloud storage only Microsoft harvests user data No zero-knowledge encryption Who Is OneDrive For? Microsoft product users: OneDrive comes preinstalled on Windows devices and integrates with other Microsoft products, such as Office and SharePoint, making it great for Windows users. Heavy Microsoft Office users: If the online version of Office isn’t enough for your needs, higher-tier OneDrive subscriptions come bundled with the full versions of all Office apps. That’s a great deal if you’re planning on paying for an Office licence. What Does OneDrive Do? Microsoft OneDrive is one of the biggest cloud storage providers. It comes preinstalled on every Windows computer. Though it’s not as secure as other cloud services, it comes with a host of useful features, mostly related to its integration with Microsoft’s other products, such as the Office productivity suite and SharePoint. OneDrive Hands-On Testing OneDrive’s apps are available on iOS, Android, Windows and Mac operating systems, though Windows users will have the best user experience, as there’s no setup or installation involved. The desktop apps use the sync folder method. You have the option to mark some files as “on demand,” which makes them available only in the cloud to save space on your computer. If you open one of these files, it will temporarily download onto your device until you mark it as “on demand” again. OneDrive’s web interface supports in-browser previews for over 300 file types, including CAD drawings, 3D models and medical imaging formats, eliminating the need to download or install specialized software while maintaining original file fidelity. Notes From the Lab: OneDrive Speed Test Results Unsurprisingly, OneDrive is one of the fastest services we’ve tested, tying with Icedrive for third place overall. Though its upload speeds were average, its downloads were the second fastest in our test. CPU usage was low, but RAM usage was surprisingly high. Notes From the Lab: OneDrive Security Analysis Key Security & Privacy Features: Two-factor authentication Password protection for vault files We won’t knock OneDrive’s security. We’re fairly certain it’s next to impossible to crack a Microsoft server, so you won’t have to worry about hackers. However, the true privacy risk here is Microsoft itself. With no zero-knowledge encryption, Microsoft can harvest your data, and the U.S.’ espionage practices and lax privacy laws make this particularly worrying. OneDrive Pricing & Value OneDrive isn’t strictly expensive, but you won’t get much cloud storage. Free users get 5GB of OneDrive storage, while personal users can get up to 1TB of cloud storage. The 1TB plan is available only in a bundle with Microsoft 365, costing $8.33 per month. Read our OneDrive review for more. Comes with Office 365 Personal Comes with Office 365 Home 11. Google Drive — Best Cloud Storage for Collaboration Google Workspace integration Excellent sharing & collaboration Video player with advanced playback options No Linux support Google harvests user data No zero-knowledge encryption Who Is Google Drive For? Google Workspace users: Google Drive integrates with most Google apps, including the Google Workspace suite . Paired with granular access controls for shared files, this makes Google Drive a powerhouse for collaboration. Videographers and video editors: If you’re a YouTuber, you’ll find Google Drive’s video player useful, letting you comment on videos, generate captions, and integrate with third-party YouTube uploaders. What Does Google Drive Do? Google Drive is an absolute giant in the cloud storage industry. It’s the most popular cloud storage service by a wide berth, though that’s mostly due to all Google services (like Gmail) using it for storage. It integrates with all Google products, including Google Docs, Sheets and Slides, and it offers a whole store of third-party integrations as well. Google Drive Hands-On Testing For device support, Google Drive is available on Mac, Windows and both mobile operating systems, coming preinstalled on Android. Its mobile app doesn’t support automatic photo uploads — that’s done via Google Photos, which is a separate app. Note that Google Photos supports only two-way syncing, which means you can’t delete photos on your device without also deleting them from your cloud storage. Notes From the Lab: Google Drive Speed Test Results Google Drive’s speeds remain largely unchanged since we last tested it. This is good, though, as it has the second fastest speeds of any cloud storage service, second only to IDrive. The CPU load was high to start but decreased significantly later on during testing. Notes From the Lab: Google Drive Security Analysis Key Security & Privacy Features: Hardened servers Two-factor authentication Independent security audits With Google Drive, you’re putting your private files in the hands of the most data-hungry corporation in the world. The lack of zero-knowledge encryption means Google can access and scan files as it pleases. This makes it hard for us to recommend Google Drive, though you may find it worth trading some data for its broad feature set and collaboration options. Google Drive Pricing & Value Free users get 15GB of Google Drive storage, which seems generous. However, the storage is shared with Gmail and Workspace, which presents some issues. For example, if Google Photos eats up your entire free storage space (as it is likely to do quickly), you won’t be able to send or receive Gmail emails, as there won’t be any space left for Gmail storage. Fortunately, Google Drive’s paid plans are fairly priced, with its 2TB plan costing $8.33 per month on a yearly subscription. Paid plans go all the way up to 30TB , though you might have to contact support to get more than 5TB cloud storage. Read our Google Drive review for the full scoop. *The plan is “hidden.” To find the 200GB plan, you need to be subscribed to one of the other plans, upgrade or downgrade to the 200GB through your account’s settings. 12. Dropbox — Best Cross-Platform Desktop Apps Reliable syncing Streamlined apps Microsoft Office integration Google Workspace integration Not the cheapest Past security breaches Who Is Dropbox For? Cloud storage beginners: Dropbox provides one of the most streamlined cloud storage experiences. With apps for all major OSes, fast speeds and instant syncing, coupled with an easy-to-use sync folder, this makes it a great choice for beginners. What Does Dropbox Do? Dropbox is the OG cloud storage service, having launched in 2008. It lets you collaborate online via both Google Workspace and Microsoft Office, and it has an app store for other third-party integrations. However, it’s had some serious security breaches. Though it’s addressed all of them, we still have a hard time recommending it for storing sensitive files. Dropbox Hands-On Testing Dropbox’s desktop and mobile apps are polished to a T and are among the easiest to use. It popularized the sync folder method and has since perfected it with the addition of selective syncing. Though we frequently get reports in our comments section of other cloud services not syncing files properly, we’ve never received any such complaints for Dropbox, thanks to its excellent syncing technology. Dropbox’s “smart sync” feature intelligently manages local storage by keeping rarely accessed files in the cloud while maintaining their visibility in your file explorer, helping preserve precious disk space. The web interface also includes built-in file preview capabilities for over 30 file types, eliminating the need to download files just to view their contents. In addition, Dropbox Business users can access the remote device wipe capabilities, allowing them to protect their data by removing access from lost or stolen devices. The service even provides robust APIs for developer integration, so businesses can build custom applications that interact directly with their cloud storage infrastructure. Notes From the Lab: Dropbox Speed Test Results Another big name on the list, Dropbox has unsurprisingly decent speeds, though they’re still not up to par with the heavier hitters. It’s a well-rounded performer overall, with above-average uploads and downloads. CPU usage remained low throughout testing. Notes From the Lab: Dropbox Security Analysis Key Security & Privacy Features: Two-factor authentication Being a big name in cloud storage but lacking the budget of Google or Microsoft, Dropbox has been the target of multiple successful cyberattacks. Its controversies are worthy of an entire Wikipedia page . Dropbox lacks zero-knowledge encryption and was even considered for inclusion in the U.S.’ PRISM program , so your data may not be fully private. Despite Dropbox’s past security issues, its Enterprise plans now include comprehensive authentication logging that records every login attempt, device used, location and administrative action, allowing security teams to identify suspicious access patterns and potential account compromise in real time. Dropbox Pricing & Value Dropbox’s free plan comes with a paltry 2GB of free storage. Its paid plans aren’t exactly cheap, but they’re not quite as expensive as some others, with a 2TB Dropbox account costing $9.99 per month on a yearly subscription. Read our full Dropbox review to get the full picture. (Formerly Dropbox One) 1 user Signature requests and eSignature templates 3 users minimum 3 users minimum 13. Box — Best Cloud Storage for Business Task management Integrates with Box apps Office & Workspace integration Outrageously expensive Zero-knowledge costs extra Iittle storage space for personal use Who Is Box For? Small businesses and large companies: Box is primarily aimed at business users, offering its own suite of productivity apps, as well as a host of integrations with third-party apps. It even has an admin console that lets you manage user access levels and permissions, and monitor their activity. What Does Box Do? Box is a business-oriented cloud storage platform that offers strong collaboration features. With its deep Microsoft Office and Google Workspace integrations, it lets you edit files directly within the Box app, even on mobile. Box also offers its own apps that integrate with its cloud storage, as well as a long list of third-party integrations. Box Hands-On Testing Box has apps for Windows, Mac, iOS and Android, and we generally like how they handle. The desktop apps can seem overwhelming though, and the mobile apps upload directly to the root folder instead of a dedicated folder. The service also provides a comprehensive REST API that enables developers to integrate cloud storage functionality into custom applications and automate storage-related workflows. Notes From the Lab: Box Speed Test Results Unfortunately, Box’s speeds are slow compared to competitors, exhibiting average to low speeds for uploads and downloads. We noticed the larger files in our test folder affected this the most, causing uploads to come to a halt at times. It’s likely that if you upload only small files, the speeds would improve greatly. CPU and RAM usage remained low in our tests. Notes From the Lab: Box Security Analysis Despite being a U.S.-based company, Box’s use of zero-knowledge encryption means your data should be safe with the company. However, keep in mind that you will need to enable it manually, and it’s unfortunately available only to business users. Box maintains SOC compliance certifications, demonstrating its commitment to maintaining strict security controls and processes that meet industry standards for enterprise data protection. It has also achieved FedRAMP High certification, making it suitable for government agencies and contractors requiring stringent security controls for handling sensitive federal information. Box Pricing & Value Even considering how much value you get, we believe Box is exorbitantly expensive. You’ll pay $10 per month for a mere 100GB of storage. Plus, zero-knowledge security costs extra, and you’ll have to go through a sales agent to get it. Its free plan offers 10GB , which is enough to try out the service. Box’s higher-tier enterprise plans include seamless integration with major identity providers like Okta, Azure AD and Google Workspace. This enables features like single sign-on (SSO), centralized user provisioning and automated access revocation when employees leave the organization. Read our Box review for more.

Apple users: iCloud is an OK choice for Apple users looking for convenience, as it comes preinstalled on Apple devices like Macbooks and iPhones. However, it’s not the fastest service, has limited free space, and lacks any useful cloud storage features, so we find it hard to recommend. What Does iCloud Do? Apple’s iCloud isn’t exactly the best cloud storage service. It’s slow and has no useful features. The best we can say about it is that it’s already there if you’re an Apple user. In fact, it ranks last in our guide to the best cloud storage for Mac ; we tentatively included it due to its recent addition of end-to-end encryption, which at least makes it more secure. iCloud Hands-On Testing Unsurprisingly, iCloud works on all Apple devices. It even supports Windows, but not Linux or Android. Its apps are easy to use, but that’s not saying much considering there are virtually no features that could cause any confusion. Syncing happens via the iCloud Drive folder, and there’s selective syncing to help save space. Notes From the Lab: iCloud Speed Test Results Though iCloud’s speeds have improved since our last round of testing, it remains one of the worst performers in the group. It had the worst download speed test results, the third worst upload speeds and is the second overall slowest service. Notes From the Lab: iCloud Security Analysis Key Security & Privacy Features: Two-factor authentication Client-side encryption (with exceptions) iCloud isn’t exactly well known for its security. If anything, it’s been considered one of the worst services for privacy since the 2014 celebrity photo leak . However, it’s improved its security since then, even offering Apple’s somewhat limited version of zero-knowledge encryption. Apple’s “advanced protection” feature lets you keep your own encryption keys, but some metadata remains visible to Apple. Notably, this includes each file’s original checksum, in an effort to fight copyright violations and CSAM distribution. This means iCloud still isn’t truly zero-knowledge. iCloud Pricing & Value The iCloud free plan comes with just 5GB of free storage, which you can upgrade to 12TB . The 2TB plan costs $9.99 per month. This is too much considering the dearth of features iCloud offers, but otherwise it isn’t too bad. Our full iCloud review has more information on Apple’s cloud service. Our Methodology: How We Tested the Best Online Cloud Storage Services Before we make any decisions, our team of experts spends a week familiarizing themselves with the services we review. We focus on aspects that most impact the user, with a particular focus on security and privacy. Security and privacy: We analyze the encryption technology behind the service, looking at the ciphers used, server security and any past breaches. We also pore over the privacy policy for any suspicious language, and we check whether the servers are located in countries with poor or strong privacy laws. Speed: We periodically run speed tests by uploading and downloading a 5GB test folder to the cloud twice and averaging the speeds. The tests run on a virtual machine hosted in Dublin, Ireland, over a 100 Mbps symmetrical connection. Collaboration and productivity: We look for features like integrations with productivity suites, and advanced sharing and permission settings. CPU and RAM usage: We use software called SysGauge to create a five-minute rolling average of CPU loads, RAM usage and thread counts. Ease of use: Throughout our testing, we note any difficulties or pleasant surprises we’ve had while using the service. Price and value: We compare all of the above factors with the price per month on a 2TB plan (or closest) to determine a service’s value. Is Cloud Storage Safe? Cloud storage on principle is safer than local storage, as there’s next to no risk of losing your data to device failure, computer viruses, cyberattacks or acts of nature. However, you need to choose your cloud service carefully. Opt for one that offers data encryption — in particular, client-side, zero-knowledge encryption. When choosing a cloud storage provider, check their service-level agreement (SLA), which outlines their guaranteed uptime, performance metrics and compensation policies if these standards aren’t met. Free vs Paid Cloud Storage Providers Comparing free vs paid cloud storage services is like choosing between crashing on a friend’s couch and renting a hotel room — one is free but comes with severe limitations, while the other is more expensive but comes with better privacy, and more space and convenience. While most cloud storage services offer free plans, these often come with limitations. The table below compares features commonly found in free and paid cloud storage services. Keep in mind that this table isn’t comprehensive or reflective of every cloud storage service, as these are just general commonalities we’ve discerned from our experience working with cloud services. The Limitations of Free Cloud Space There are multiple ways in which free cloud storage services limit your experience, the amount of storage space you get being the most obvious limiting factor. Free cloud services often cap their storage, rarely exceeding 20GB. They also limit the features available to you, such as collaboration options. Some free cloud services might also be less safe to use than their paid counterparts. For example, services with client-side encryption will often make this key privacy feature exclusive to paid users. Sketchier services might even scan your data to sell to advertisers, which is why it’s important to read the service’s privacy policy before subscribing. On the other hand, paid services come with much more cloud storage, depending on your subscription. They also come with more features, such as advanced sharing and integrations with third-party productivity suites. Some are also more private thanks to the inclusion of client-side encryption, though a few services like Sync.com and MEGA offer this for free. Is Free Cloud Storage Secure Enough? Besides the frequent exclusion of client-side encryption, free cloud services sometimes omit other key privacy and security features. For example, some might not include two-factor authentication, which protects your logins in case your account info leaks There are also limits on features not strictly related to security, which can nonetheless impact your privacy. For example, if a service hides advanced sharing features or folder access permissions behind a paywall, you might inadvertently allow someone to download a file you wanted to show only them, or they might share it with an unintended recipient. How Much Free Cloud Storage Can You Get? Free cloud space is usually limited, though there might be ways to expand it, such as performing micro-actions or referring new users to the service. The following table presents an overview of the default and maximum storage amounts you can get with a selection of providers. Some cloud storage services offer large amounts of storage for free. These services are often scams or come with much more severe limitations than other free cloud storage providers. To monetize these services, companies might include ads in their applications, scan your files for data that they can sell to advertisers, host your files on slow servers, and even skip on encryption entirely. Guide: How to Maximize Cloud Storage – Get 100GB for Free If you don’t want to use a sketchy service like TeraBox, there are ways you can get 100GB of free cloud storage or more by combining multiple free accounts, as the below guide shows. Create a new account with MEGA to get 20GB of free cloud storage. Repeat until you’ve created five accounts with 100GB of total storage between them.
