The best cloud storage providers available
IDrive is, in our opinion, the best cloud storage service available to premium users, offering great value for money as well as highly secure storage. Arguably the biggest advantage is that it applies to network drives too, meaning everything from servers to mobile devices is covered. Users can share files via email, Facebook and Twitter, and restore up to 30 previous versions of back-ups.
Speaking of backup, IDrive Express provides a physical hard disk drive in case you lose all of your data, making a backup quick and painless (disk image backup is also covered). The service doesn’t automatically delete cloud files if you delete something on your hardware, so there’s no risk in completely erasing valuable data by accident.
IDrive also ranks first among the best cloud storage for photos, and photo-minded users will be happy to hear there’s a facial recognition feature that automatically organizes images, and syncs them across all linked devices. Plans start at $79.50 a year for one user, unlimited devices and 5TB of storage (the IDrive Personal plan), while IDrive Team offers five users, five computers and 5TB for $99.50 a year.
For personal and professional projects, Google Drive is the natural go-to for Google Workspace and Android users, due to seamless integration and versatility. You can use the office suite to create and store documents, spreadsheets, presentations, and more; and store mobile-based high-quality photos via Google Photos.
While the web interface is somewhat poorly executed and not as user-friendly as elsewhere, native clients allow Windows and Mac users easier file storage through drag-and-drop. There's a 15GB free storage plan, and you can buy more via Google One, starting at $1.99 a month or $19.99 a year for 100GB (when paid annually).
Each subscription can be shared for free with up to five others, but everyone will have to share the same amount of storage. Upgrading to 200GB costs $2.99 a month or $29.99 a year, with 3% cashback in store credit from the Google Store; 2TB of storage and 10% cashback costs $9.99 a month or $99.99 a year.
While this isn’t always clear online, additional storage is also available through Google Workspace. 30GB is available for $6 per user a month, while unlimited storage for teams of five or more users costs $12 per user a month. For $25 per user a month, you’ll also get priority support, data loss prevention, and other perks.
Technically speaking, Nextcloud is not an online cloud storage provider on its own. Rather, it's a self-hosted file sync and content collaboration platform, which provides free software you can install on your own server, and administer cloud storage services yourself.
The benefit of a self-hosted product is that you get to keep your data on your servers, offering complete control and faster performance. While this might seem intimidating for beginners, or futile for serverless users, the service offers preconfigured hardware that runs Nextcloud out of the box.
As free open-source software, you can download and install it at no cost, but need to factor in the cost of setting up, running, and administering your own servers. However, if you already have infrastructure in place, using Nextcloud instead of a commercial cloud storage solution could save you money.
There are three pricing plans as an alternative, namely the Basic, Standard, and Premium plans, which are pre-configured and ready to go. These are billed annually, with no monthly payment plans available: Basic costs $42.60 per user a year (based on 100 users) or $33.72 (based on 200 users); Standard costs $76.90 or $57.38; and Premium $112.99 or $88.14.
Third-party providers can deploy, optimize, and maintain your Nextcloud installation for you, and if you have at least 50 users, you can choose Nextcloud Enterprise, a pre-configured, production-ready version. Read our Nextcloud review for more information.
Hailing from Switzerland, pCloud offers no file size limit, making it ideal for storing large media files, although there are some bandwidth limits. You can also send up to 5GB for free with pCloud Transfer, which covers all desktop and mobile platforms, and also has a web-based login. You can also spend more on a monthly, annual or lifetime basis for pCloud Crypto, which can encrypt individual files.
It’s worth noting that pricing plans include lifetime subscriptions, a fairly unusual sight when it comes to cloud services. Each plan comes with unlimited remote upload traffic and 30 days trash history, with the difference being the amount of storage and download link traffic: 500GB for the Premium package, and 2TB for the Premium Plus package, which cost $4.99 or $9.99 a month, or $47.88 or $95.88 a year respectively.
One quick look at pricing, and it’s clear Box is prioritizing businesses as its key demographic. However, it offers both individual and business plans, and Box's pricing structure is very simple for the former.
You pay nothing for up to 10GB of storage, with a maximum file size of 250MB, or $10 a month for the Personal Pro plan, with up to 100GB of storage and a maximum file size of 5GB. Box apps for desktop cover Windows and Mac, while mobile users can use the official Android client.
With almost 15 years in the sector, Box is a mainstay in cloud content management and file sharing. Its strong points include broad management abilities and an emphasis on security, while its UI is easy to navigate, making you feel you at home immediately. It's supported by a variety of commonly used app packages, including Google Workspace and Microsoft 365.
Ever since the switch to Windows 10, OneDrive has been the Microsoft cloud storage solution of choice. It's directly integrated into the file explorer, providing immediate access for users who want to jumpstart their online backup. There are also Android and iOS apps for mobile uploads, as well as an improved app for Mac users.
As a Microsoft platform, OneDrive works closely with Microsoft 365, which is helpful if you're looking to boost productivity. The Photos app can sync images across all your devices, and you can selectively sync files stored on your hard drive. The mobile app offers interesting features, such as multi-page scanning that allows you to save them as a single document, and access anywhere from any device.
OneDrive has plans for home and business use, with four for home: two of these are OneDrive only, while the others incorporate Microsoft 365. Prices range from the free Basic plan offering 5GB of storage, up to $9.99 a month ($99.99 a year), to 6TB with the Microsoft 365 Family plan, which accommodates up to six people (1TB per person). Microsoft 365 plans offer Outlook, Word, Excel, PowerPoint, and Skype.
The most expensive plans also come with a one-month free trial. For more information, read our Microsoft OneDrive review.
Zero knowledge cloud storage pertains to encryption, which, according to SpiderOak, takes place before syncing, so it has no idea what you're storing. You're the only one who knows what's being encrypted and saved, which makes your data utterly private. The source code isn’t public though, so you’ll just have to take SpiderOak’s word for it.
There's a 21-day free trial available, so you can see how the service works and test it before buying, and considering the focus is on security and privacy, it has a simple and straightforward interface, which utilizes a convenient drag-and-drop feature to help with quick and efficient file organization.
There is native support for Windows, Mac, Linux, Android, and iOS, although the mobile apps are read-only and don’t allow you to upload files. SpiderOak One has four pricing plans, with the cheapest at $6 a month including 150GB of storage and support for unlimited devices.
For $11 a month, you get 400GB of storage, and 2TB for $14 a month, while $29 a month gets you 5TB, with a small discount of around 5% if you pay annually. Find out more by reading our SpiderOak review.
Right on the heels of Microsoft, Apple’s own cloud storage delivers a sound service. Even if 5GB of free storage won’t back up your iPhone or iPad entirely, the paid subscriptions are competitively priced.
The standout feature is how easily accessible the service is across Apple’s platforms. For instance, you can store anything through the Mac Finder app, which integrates with iCloud Drive, and also sync iWork documents across all your devices, which are saved to iCloud.
If you’re a Windows user with an iPhone, you can also sync files with iCloud Drive via the official client, as well as use the iCloud website to access iWork apps. iCloud's 5GB for free is better than other providers, but significantly less than the 15GB available with Google Drive.
Additional storage is available at different prices, with 50GB for $0.99 a month, 200GB for $2.99 a month, or 2TB for $9.99 a month. Unfortunately, there aren’t any long-term subscriptions, which could be a significant disadvantage for some users. To learn more, read our full iCloud review.
A 50GB free plan is a real rarity in cloud storage, so MEGA delivers right from the start. Add in an easy-to-use, drag-and-drop interface, and you have one of the best cloud storage solutions. A mobile app allows uploading of files and photos, while desktop users have sync clients at their disposal.
The invention of the infamous Kim Dotcom, MEGA allows you to upload files via an encrypted connection, and maintain control over your encryption key. That effectively prevents others, including MEGA, from scanning your content. In addition, its sync client is open-source and open to vulnerability checks.
For those seeking a paid option, there are four tiers ranging from Pro Lite to Pro III: the only main difference being storage and transfer amounts (all four maintain the same additional features). There's also a Business plan with 15TB of storage, unlimited data transfer, and other features, starting at $5.89 per user.
Pro Lite has 400GB of storage and a 1TB transfer limit per month for $5.88, with the others offering 2TB storage and transfer (Pro I at $11.78 a month), 8TB storage and transfer (Pro II at $23.56 a month) and 16TB storage and transfer (Pro III at $35.35 a month).

What is cloud storage?
Cloud storage stores data on a physical drive, and makes it accessible to users whenever and wherever they want to view it via an online software platform. There are three main forms:
- self-hosted, using on-premises (on-prem) infrastructure
- storage as a service (StaaS), using externally-managed infrastructure in data centers, allowing for economy of scale and large, affordable storage levels
- hybrid cloud storage, combining on-prem infrastructure and cloud networking
StaaS products are almost always more affordable per TB, and are often known as storage and syncing platforms as they're designed for collaboration. Their services give users the ability to seamlessly upload, access, edit, and share data from any connected device, thanks to cloud sync technology.
This encompasses file versioning and link sharing, allowing for file sharing, tracked document changes, edit incorporations, and more. Accordingly, StaaS cloud storage products provide a cohesive, integrated digital environment, and rank among the best apps to share files.
How secure is cloud storage?
The best cloud storage services provide leading security and encryption, despite theoretically not being as secure as local storage. Two highly-desirable features to look for are end-to-end encryption and zero-knowledge architecture: respectively meaning providers are essentially hack-proof, and that not even staff can access your data, even if law enforcement compels them to.
It's also worth looking for in-transit and at-rest encryption if end-to-end isn't offered: data is totally indecipherable even should a cybercriminal intercept it. StaaS organizations utilize highly-secure data centers, protected by 24/7 security, biometric entry authorization, and frequent auditing.
Make sure to look out for extra features like 2FA: while it's only natural to have concerns about data security, the best cloud storage services' strong features and security tools are cutting-edge.
How we review the best cloud storage platforms
When we review cloud storage providers, we test upload and download times for files, as these speeds are integral to performance and usage. We also look at how each provider's security stacks up, how responsive their customer service teams are when there's a problem, at pricing, and at any additional features offered.
Our comprehensive reviews also make a point of comparing each cloud storage service to competitors, across key features and pricing, so you can benefit from as much information as possible before you make your choice.
How to choose the best cloud storage for business
When looking for the best cloud storage for business, there are key differences to personal cloud storage. Business cloud storage has to be stable, highly secure, and able to protect sensitive and important company data. As a result, look for services offering end-to-end encryption and zero-knowledge architecture.
Most business cloud storage providers are StaaS services, providing collaborative functionality and seamless digital workflows to facilitate and increase collaboration and productivity. These elements are particularly important to businesses with a blend of remote and office workers in a hybrid workspace.
Cloud sync technology allows for document edits to be immediately visible across all connected devices, and to all users given access. Business cloud storage providers also usually provide important administrative tools for access management and system usage auditing, such as roles-based permissions and 2FA.
What you need to know about free cloud storage
Because of the constantly changing market in cloud storage, many services offer free plans for users seeking basic storage, or with little to no budget. While these offer lower maximum storage capacities and fewer features, they're often ideal for the average person's needs, such as backing up documents or photos.
Even a small amount of storage makes a huge difference to the majority of users, who can securely save copies of important files for quick and easy access. If you require more space, it's simple to upgrade to premium plans offered by many free providers.
Another benefit of the best free cloud storage is the ability to utilize it for collaboration on small projects, which is ideal for freelancers, for example. However, take into account that while free plans are ideal for some, their limitations can be an issue.
