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. 

1. Box Business — Best Unlimited Cloud Storage

More details about Box Business:

  • Pricing: Unlimited storage from $15 per month (one-year plan)
  • Free plan: 10GB free plan, 14-day free trial for paid plans
  • Provider website: box.com

Pros:

  • Excellent file sharing tools
  • Unlimited business storage
  • Unlimited business users

Cons:

  • Relatively slow speeds
  • No block-level sync

Box Business is one of the few cloud storage solutions that offer multiple plans with unlimited storage space. Except for the Business Starter plan, any business plan you choose includes unlimited space. Another business plan feature is unlimited team size, meaning plans are flexible enough for smaller teams or enterprise-sized organizations.

The Box Business plans include excellent file versioning, letting you keep up to 50 versions of a file. The Enterprise Plus plan includes unlimited file versioning. For productivity and collaboration needs, companies have many choices for external integrations. The two most prominent are Google Workspace and Microsoft 365. 

Box Business Hands-On Testing

Box Business is easy to navigate as it has a familiar left sidebar layout in the middle of the page, putting your data easily within reach. When you select an item, a right sidebar opens that provides additional information, including the option to enable sync to your desktop with folders.

  • Pricing: Unlimited storage from $18 per month (one-month plan)

Sync.com for Teams Hands-On Testing

Sync.com opts for a more traditional menu across the top of the web page to navigate around your account. The result is a somewhat dated look and feel. Selecting either a folder or a file increases the choices found in the right-side menu. The desktop app is limited to a sync folder and options from the menu bar.

Sync.com’s desktop app focuses on the sync folder, letting you

Sync.com cloud storage service has zero-knowledge
encryption that protects an entire account.

Security and privacy are two hallmarks of Sync.com’s service. It has zero-knowledge encryption that protects all the contents of an account. You can opt to have Sync.com send you an email to reset your password or provide a password hint. However, failing to do so means you are locked out if you forget your password, as Sync.com does not have access to your account.

3. Jottacloud

Jottacloud’s clean and uncluttered interface uses the familiar left sidebar for navigation.

More details about Jottacloud:

  • Pricing: Unlimited storage from $9.90 per month (one-month plan)
  • Free plan: 5GB free plan
  • Provider website: jottacloud.com

Pros:

  • Unlimited backup
  • Perfect for photos
  • Inexpensive plans

Cons:

  • No block-level backup
  • No individual file backup

Jottacloud is the first cloud storage service on our list with unlimited cloud storage for personal use, although with a catch. Yes, you get unlimited cloud storage space. However, if you exceed 5TB of data, Jottacloud will limit your transfer speeds. It is not a dealbreaker for some, but it is something to be aware of.

Jottacloud is a solid option to store your photos. When you upload your images, Jottacloud won’t compress them, although no editing tools are included. You can play videos from the web browser or create photo albums. Jottacloud has an AI-powered photo search feature that does a good job of finding images using descriptive phrases.

Jottacloud Hands-On Testing

Jottacloud takes a simplified visual approach to its web interface. The photo tab organizes your photos from the date taken, not the date uploaded. The sync folder on your desktop lets you add or remove files, and the desktop interface supports selective sync.

jottacloud microsoft
Jottacloud integrates with Microsoft 365, letting you create
and edit files for Word, Excel or PowerPoint.

Notes From the Lab: Jottacloud Speed Test Results

Jottacloud is slower with uploads, averaging close to nine minutes, transferring a combination of 5GB of data. Downloads were faster, averaging around seven minutes.

Jottacloud uses AES-256 encryption and TLS/SSL encryption protocols to protect your data at rest and in transit. Additionally, you can enable two-factor authentication on your account. Sharing is not a secure experience, as you can’t add a password, limit downloads or set a link expiration date.

Jottacloud Pricing & Value

Jottacloud offers a free 5GB plan, making testing the service easy. You’ll need to purchase the Personal plan for unlimited cloud storage, which costs $9.90 per month or $99 per year. Note, prices are in Euro, so actual USD prices will fluctuate with exchange rates. Read our Jottacloud review for more on pricing and features.

4. Backblaze

backblaze account
Backblaze is an online backup provider with elements of a cloud storage service.

More details about Backblaze:

  • 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.

Backblaze Hands-On Testing

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.

Backblaze-Main-Panel
Backblaze’s control panel lets you control and customize your online backups.

Notes From the Lab: Backblaze Speed Test Results

Backblaze is not one of the fastest online backup services we’ve tested. Uploads were exceptionally slow, given how the service handles multithreading — it separates them, which can lead to speed throttling — while downloads were faster, averaging eight minutes.

Backblaze Pricing & Value

Backblaze has one plan with the option to pay by the month, year or two years. It does offer a 15-day free trial to try it out. Purchasing costs $9 per month, $99 annually, or $189 for two years. We cover pricing in our Backblaze pricing guide and go in-depth with our Backblaze review

5. OpenDrive

OpenDrive’s web interface has a dated look, although it does have
a dedicated space for your music and photos.

More details about OpenDrive:

  • Pricing: Unlimited storage from $8.25 per month (one-year plan)
  • Free plan: 5GB free plan, 7-day free trial for paid plans
  • Provider website: opendrive.com

Pros:

  • Unlimited cloud storage
  • Zero-knowledge folder
  • Shared personal accounts 

Cons:

  • Poor speeds
  • Dated interface

OpenDrive offers unlimited cloud storage for both personal and business plans, and it is one of the few cloud storage solutions to do so. Another unique feature is adding multiple users to a personal account, often reserved for business plans. 

OpenDrive has many of the standard cloud storage features you’d expect, like file sharing and sync. What sets it apart from competitors is that it offers project management tools. Some features and options include creating and assigning tasks, determining priority levels and setting due dates. The number of tasks you can create is directly tied to your plan.

OpenDrive Hands-On Testing

The web interface has an older, dated look and feel, although it does not impact navigating around your account or working with your data. Each account includes folders dedicated to music and photos.

OpenDrive has a simplified note-taking app built into every account,
which works well with its project management features.

Notes From the Lab: OpenDrive Speed Test Results
