Cloudwards Editor’s Choice
Box Business is our top choice as every plan — except Business Starter — comes with unlimited cloud storage. Overall, Box Business is a feature-rich experience with plenty of external integrations to popular productivity apps. Accounts come with native apps like Box Notes. Administrators and managers have several tools and settings to manage users, teams and data.
How to Choose the Best Unlimited Cloud Storage
Price is a major factor, as no cloud provider offers unlimited free storage. The cloud storage options geared toward businesses require more than one user, making it an expensive option for individuals.
How well a cloud storage secures and protects your data is important, since it would be pointless to store your data unsecured. If data privacy is your top consideration, choosing a provider offering zero-knowledge encryption is the best option. With zero knowledge, you avoid unauthorized access to your account as you are the only one with the password.
The 5 Best Unlimited Cloud Storage Options
Box Business tops our list of unlimited cloud storage services, as many of its business plans have unlimited cloud storage. Sync.com for Teams also has a business-focused plan with unlimited cloud storage. JottaCloud is the first on the list to offer unlimited personal cloud storage.

- Pricing: Unlimited storage from $7.88 per month (two-year plan)
- Free plan: 15-day free trial
- Provider website: backblaze.com
Pros:
- Unlimited backup
- Great pricing
- File sharing capabilities
Cons:
- Few features
- No mobile backup
Backblaze is a great option if you want unlimited cloud storage and aren’t looking for a feature-rich experience. It handles most file types as Backblaze is an online backup service more than it is a traditional cloud storage provider. However, you can share files by creating a link.
Backblaze is not the same as Backblaze B2, so don’t confuse the two, even if they look similar visually. The unlimited cloud storage for one price is Backblaze, while Backblaze B2 is object storage for servers. We cover more in our Backblaze B2 review.

Visually, Backblaze uses what looks like cards to compartmentalize your backups. Clicking on a card pulls up more information and options. Accessing your data, uploading files or restoring from a backup is easy.
