What is cloud storage?

Cloud storage is a virtual storage space hosted by a third party that allows users to securely access the data at any time from any location, such as a web browser, desktop application, or mobile app. Files and folders stored in the cloud can be easily shared with others by granting permission.

How does cloud storage work?

Cloud storage works by saving your data or files to remote servers. When you click save on your computer, the file is saved to the computer’s hard drive. However, when you save something to the cloud, it sends it over the internet to the server hosting your cloud’s data. Think of cloud storage as a virtual hard drive accessible from anywhere, so instead of having a hard drive backup, you have a cloud backup.

Top Cloud Storage Solutions


Best for lifetime subscriptions

pCloud offers secure and simple cloud storage for both personal and professional digital assets. Security takes on a whole new meaning with pCloud Crypto; a zero-knowledge file encryption feature to protect sensitive data. Not only does pCloud pack tons of impressive features into all of their plans, but every tier also offers unlimited devices and the option for a lifetime subscription. You won’t find many cloud storage services offering these kinds of perks. pCloud is a fantastic choice in terms of value for all types of cloud storage needs with the added bonus of speedy file syncing and sharing that makes other cloud storage providers look like turtle on a Sunday stroll. pCloud pricing starts at $175 (500GB) for a lifetime personal subscription and $7.99 (1TB per user) a month for business users.

Lifetime Subscription

pCloud is the only cloud storage service that offers individual accounts the option to purchase a lifetime subscription for one fee. We aren’t usually the ones to suggest a lifetime commitment, but we’ll make an exception for these premium features.

pCloud Crypto

pCloud Crypto is one of the most secure ways to encrypt your data. Encrypted files can only be seen and accessed from your storage when you unlock them by entering your encryption password (Crypto Pass).

Unlimited File Size

As long as you have enough space in your pCloud account, there is absolutely no limit on the size of files and folders that you can upload and share. If you work with large files that tend to put a strain on storage, then this feature could be a real lifesaver.

Best for backup only

Backblaze is sleek and minimalistic, but don’t let that fool you; this service is making waves in the cloud storage marketplace.

Best for mobile app integration

Sugarsync is powerful and simple—two major things to look for in a cloud storage service. Sugarsync will automatically sync as many folders as you want, eliminating the need to fill your brain with mental notes of where you saved the most recent file version. When it comes to security, the latest version has introduced a feature called protected folders that is similar to file versioning, letting you keep up to 12 file versions. TLS (Transport Layer Security) ensures your files are protected during transfer, while 256-bit AES encryption safeguards them in the cloud. The desktop app is sleek and easy to use, but what makes Sugarsync stand out is how impressive the mobile app is. Personal cloud storage plans start at 7.49 per month, and business plans are $55 per month.

Remote Wipe

This powerful tool makes it easy to remove all synchronized files from any computer in the event of lost or stolen data. Since data is backed up to the cloud, you can recover all of your folders on a new device.

Protected Folders

All data is encrypted before leaving SugarSync servers. You can easily restore and share files from any computer or mobile device with the peace of mind knowing that your data is secure.

Send files of any size remotely from your mobile phone or tablet, even if your computers are turned off. Sugarsync lets you browse, sync, share, access, and backup files all from the intuitive app for iOS and Android.

We assessed cloud storage services based on storage space, network security, affordability, and ease-of-use. We also scored our list of top-rated products out of 5 points to help you find the right solution for your storage needs.

Secure cloud storage is crucial for protecting corporate data. The internet is a vulnerable space; we recommend choosing the most secure options, especially those that offer 2-factor authentication or encryption key methods to access your files.


Cloud storage pricing is typically based on the cost per gigabyte or terabyte per month or year. When investing in a product, you want to strike the perfect balance of satisfying your requirements without paying for features you don’t need at a price point that doesn’t break the bank.


There’s nothing worse than implementing a tool only for it to sit on the (virtual) shelf collecting dust because people can’t figure out how to use it. Choosing a user-friendly solution with a minimal learning curve will improve employee buy-in and implementation.
