The best cloud storage services allow you to free up storage space on your smartphone, laptop and other devices but they also let you keep an extra copy of your most important files in the cloud for safekeeping.
When it comes to the best cloud storage providers, most of them offer a wide range of free, personal, premium and business plans which gives you plenty of options to choose from. While their free tiers offer a good way to test them out, a personal or premium plan is worth investing in if you have a lot of files you want to store online. Likewise, in addition to cloud storage, you may also want to consider one of the best cloud backup solutions, especially if you want a simple, automated way to back up the contents of your laptop or desktop computer.
Even though there are some great free cloud storage options out there, this guide focuses on premium packages as well as the best cloud storage for business. Even if you don’t have your own business, premium plans like the ones detailed below provide you with loads of useful features and tools such as file syncing and improved security.

The best cloud storage overall
IDrive takes first in our list of the best cloud storage providers, and for good reason. It offers great value-for-money, provides highly secure cloud storage solutions, and has an option for every user.
The basic free-forever plan only supports 5GB of storage, but this should be enough for you to test it. Personal plans that support one user and unlimited devices cost $59.62 a year ($79.50 on renewal) for 5TB or $74.62 a year ($99.50 on renewal) for 10TB of storage. IDrive is also currently offering 10TB for a hugely discounted price of $3.98 for the first year — one of the most affordable high-capacity plans available, though you need to prove you're using a competitor as part of the signup.
All plans can be used on various desktop and mobile operating systems, including Windows, Mac, Linux, Android, and iOS. You can set up continuous data backup if required, and it’s even possible to create a copy of external hard drives and NAS (network-attached storage) devices.
We found that files can be accessed from anywhere with an internet connection, and file sharing is extremely easy. All plans come with the innovative IDrive Express feature, which enables you to back up files and data to a physical storage device, which is then mailed to your chosen address. This is available once per year with the Personal plans.
|Cost per month/year||Free||$5.79* / $79.50***||$8.29* / $99.50||$8.29* / $99.50|
|Number of users||One||One||Five||Unlimited|

*All prices are based on undiscounted rates of the cheapest available annual plan. Monthly plans are only available via Business packags with 1.25TB or more, starting at $49.95 a month.
**Entry-level Team and Business plans shown: plans go up to 100TB and 100 users / 50TB and 50 users.

Best cloud storage for collaboration
Google’s cloud storage walks hand in hand with Android and Google Workspace. If these platforms are already a part of your workflow, Google Drive offers a feature-rich, affordable native backup-and-sync solution.
While not as barebones as some of the other options listed, we found Google Drive’s UI to be clean and intuitive. It is worth remembering, however, that it's more than cloud storage. It comes with companion apps including Google Photos, Docs, Sheets, and Slides—together known as Google Workspace—meaning you can create, edit, store, view, and synchronize files via this unified, web-based interface.
When you open a new account, Google offers you free storage of up to 15GB on Google Drive. This plan is yours to keep forever, and if you wish to upgrade to a higher storage plan down the road, you can do so. The paid plans, offered under the banner of Google One, start at $1.99 a month for 100GB. From there, you can upgrade storage to a maximum of 30TB for $299.99 a month.
The web interface, while very attractive, isn’t the easiest to use. This problem is easily solved however by downloading the Google Drive desktop application for Windows and macOS. This file explorer-based drag-and-drop system is not dissimilar to Microsoft OneDrive, which lets you back up, store, modify, and delete files directly from your desktop.
|Cost per month/year||Free||$1.99 / $9.99||$2.99 / $29.99||$9.99 / $99.99|

Best cloud storage for file sharing
Dropbox is a fantastic choice for personal cloud storage. Plans are affordable, the user interface is impressive, and it integrates well with many third-party platforms.
It is a leader in file sharing, with several features helping to make it easy to share large files with others, whether they use Dropbox or not. However, one limitation we found is that you can’t back up external or network drives — Dropbox only stores what you transfer to the Dropbox folder on your device. This isn’t a major issue, but differentiates it from competitors like IDrive.
Security is impressive without being exceptional, with all files are encrypted at rest and in transit, though there is no end-to-end encryption. Accounts can also be secured with two-factor authentication (2FA).
It has a free plan with 2GB of storage, as well as two other personal plans. Of these, the Plus Plan is $9.99 a month for 2TB of storage, and enables you to send files up to 2GB per transfer. The Family Plan has the same storage and transfer capabilities, but for six individual users, for $16.99 a month. Despite its limitations, we think you could do much worse than Dropbox for cloud storage.
|Cost per month/year||Free||$11.99 / $119.88||$19.99 / $203.88||$19.99 / $1,198.96||$15 / $150 (per user)||$25 / $240 (per user)|
|Number of users||One||One||Six (maximum)||One||Three (minimum)||Three (minimum)|
|File versioning||✖||✔ (30-days)||✔ (30-days)||✔ (180-days)||✔ (180-days)||✔ (180-days)|
Best cloud storage for security
Sync is a simple, fast and secure cloud storage service that will appeal to those on a budget.
In fact, you can get 5GB of free cloud storage with the service but by inviting friends, creating new folders and completing other tasks, you can bump this up all the way to 27GB. If you do want to sign up for a paid subscription though, all of Sync's plans are paid annually but there is a 30-day-money-back guarantee.
The service's Solo Basic plan costs $8 per month and gets you 2TB of secure storage along with advanced sharing options. Sync's Solo Professional plan increases the storage limit to 6TB and also includes custom branding along with advanced sharing features for $20 per month.
Unlike other cloud storage services, Sync as the name suggests syncs a single folder and the data it contains between your computers and the cloud. This limitation may be a deal breaker for some while others will appreciate the service's simplicity. There's also a Vault feature for files you want to store in the cloud that aren't synced with your other devices.
In terms of security, Sync provides end-to-end encryption for all of your files both in rest and while in transit. As for native clients, the service offers desktop apps for Windows and Mac as well as mobile apps for iOS and Android though you can also use its web interface to transfer files. Sync may not have the same level of polish as Google Drive or Dropbox but it does the basics really well with plenty of online storage space for the price.

Best cloud storage for backup
Zoolz offers high-quality cloud storage backed by the Amazon Web Services (AWS) ecosystem. It boasts excellent security, including full 256-bit AES (Advanced Encryption Standard) encryption, and compliance with various legislative frameworks including HIPPA (the Health Insurance Portability and Accountability Act) and GDPR (the General Data Protection Regulation).
A fully-functional free trial is available with 50GB, enabling you to try the service before committing. Prices range from $14.99 a month for 1TB of storage to $674.99 a month for 50TB. Significant discounts are available with annual payments.
All business plans support unlimited users, unlimited server backups, and unlimited external drive connections. Users also have access to excellent 24/7 live support and a comprehensive help center.
The Zoolz desktop interface is neat and easy to navigate, and there are also mobile apps available for managing files on the go. Unfortunately, we found these are clunky and frustrating to use, while upload and download speeds can be slow, which could be an issue if frequently working with larger files.

Best cloud storage for Windows
Microsoft OneDrive is the ultimate cloud storage solution for Windows 10/11 and Microsoft 365 users, and is also available for users of macOS, Android, and iOS. It's also available for Xbox, making it possible to store precious game save files safely in the cloud.
The platform balances high-capacity storage with functional user interfaces, powerful integrations with the entire Microsoft 365 suite, and a robust security framework. Once you’re set up, it will perform as described with no further effort or stress on your part.
We found the service to be very well integrated into Windows. In essence, it enables you take away any file or folder on your desktop and access it on a variety of other devices. It also offers the ability to share files and folders with users who don’t have OneDrive.
You can also edit files directly on the cloud, without the need to download them every time. From Outlook to AutoCAD, OneDrive is compatible with a variety of different other services, both internal and third-party. Security-wise, it offers the Personal Vault feature, which lets you lock away essential files safely via 2FA and Bitlocker encryption.
If you're a Microsoft 365 subscriber, you have up to 1TB free via OneDrive. Even if you aren’t, you can test it with a forever-free capacity of 5GB. You can always expand storage later via its personal plans, with 100GB for just $1.99 a month.

Best cloud storage for simplicity
pCloud is one of the only cloud storage providers offering a lifetime subscription, providing you with 500GB for a one-time payment of $175, or 2TB for $350. Alternatively, annual plans are available for $47.88 and $95.88 respectively.
Monthly payment options are also available, and there’s a fully-functional free plan with 10GB. You can also choose a family plan, which supports up to four users. All plans come with advanced collaboration and file-sharing features, and you can even back up files from a series of third-party platforms.
Additionally, we were impressed to find that all files are protected by TLS/SSL (Transport Layer Security/Secure Sockets Layer) security, with 256-bit AES encryption. Powerful Android and iOS apps are available for mobile management, and there are tools to help you set up automatic social media uploads should you require this.
Android, iOS, Windows, Linux, and Mac operating systems are supported, and there are also browser extensions for Opera, Chrome, and Firefox. On the flipside, it lacks competitors' collaboration tools, an in-built document editor, and a smoother interface.

Cloud storage FAQs
Want to learn more about cloud storage? We’ve covered all levels of questions in our frequently-asked questions below. Knowledge is power, and having as much information as possible before you sign up to the best cloud storage services will ensure you make the right choice for your needs.
What is cloud storage?
Cloud storage stores data on a physical drive, and makes it accessible online for users via software from any internet-connected device, whenever and wherever a user wants to access them: hence the term "cloud". Some users utilize multiple cloud services in what is called a multi-cloud service.
Self-hosted cloud storage works by using on-premises (on-prem) infrastructure to provide storage, rather than managed, remotely-based servers. You need to manage these types of services yourself.
Storage as a service (StaaS) uses externally managed, third-party infrastructure and data centers, and offers large, affordable amounts of online storage. Designed for collaboration, they can also be described as storage and syncing platforms.
Cloud sync technology encompasses link sharing and file versioning, and is offered by many StaaS providers, allowing larger businesses to undertake inter-colleague collaboration, file sharing, and much more.
How much does the best cloud storage cost?
Unlike most tech and software markets, cloud storage providers often offer excellent free plans as well as paid plans. Free plans are ideal for those seeking relatively small amounts of storage, but feature storage capacity limitations, and don’t include the same high level of tools and features as paid plans.
Paid plans are available in monthly, annual, and even lifetime models, ranging from around $50 a year (this price depends entirely on factors including storage levels and additional features). Monthly plans can be as low as a few dollars a month, and in general pricing depends entirely on what plan you want, what tools and security coverage you seek, and the encryption on offer.
How secure is cloud storage?
When we compare on-prem vs cloud storage, or even cloud storage vs external hard disk drives, security is key. Cloud storage may not theoretically be as secure as local, but the best cloud storage uses cutting-edge security and encryption. So is cloud storage secure, how secure is it, and how does it protect your data?
When it comes to enterprises, cloud storage security is crucial, particularly in data and privacy-sensitive sectors, and so investing in secure cloud storage that offers state-of-the-art policies is non-negotiable. End-to-end encryption and zero-knowledge architecture mean services are almost hack-proof, and that not even a provider's staff can access your data.
In-transit and at-rest encryption mean that even in the unlikely event of a cybercriminal intercepting data, it would be indecipherable. The very best providers not only protect data, but infrastructure housing it. StaaS data centers have 24/7 security guards, biometric authorization for entry, and frequent security auditing.
Data center locations are also key for most businesses, as different countries have different data privacy laws. You'll need to make sure data is stored in a nation that complies with your data privacy obligations.
The best cloud storage for business: what you need to know
Identifying the best cloud storage for business means looking for highly stable, secure systems that protect data at all times. End-to-end encryption and zero-knowledge architecture are particularly important, but also look for StaaS products, as they offer advanced cloud sync and collaborative features for seamless digital workflows, increased employee cooperation and productivity.
Powerful administrative features provided, such as access management, system auditing, 2FA, and roles-based permissions, are also worth keeping an eye out for, particularly for medium- and large-sized organizations.
What you need to know about free cloud storage
If you've got less complex storage requirements, or have a tight budget, most providers offer free plans. While less feature-rich, with smaller storage allowances and other limitations, free cloud storage can be more than sufficient for personal needs. You can store important documents and images, but should you want more capacity, you'll have pay to upgrade. However, the advantage is that you can try out different platforms for free before you do.
How we test the best cloud storage
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 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.
