The 5 Best Unlimited Cloud Storage Providers in 2023: Features & Pricing Compared
Need a cloud provider that offers unlimited data storage space? These five providers do not cap their online storage, which is incredibly useful if you need to store a huge amount of data or you work with large file types, like raw video files or 3D images.

Nobody likes restrictions. “Unlimited” just sounds better, doesn’t it? That goes for storage space, too: better to have unlimited cloud storage than a fixed amount. Hard drives are getting bigger, but so is the demand for space, as everything — from photos to games — needs more gigabytes. This is where our picks for the best unlimited cloud storage come in.
Key Takeaways:
- Sync.com’s Teams Unlimited plan is without a doubt the best option for unlimited cloud storage.
- If you don’t mind the high price tag and potential privacy concerns, Dropbox Business is also a good option.
- If all you need is a place to store an unlimited amount of data and you don’t need a lot of bells and whistles, backup providers like Backblaze will get you the biggest bang for your buck.
All of the cloud storage providers below have no limit on the amount of data you can store with them, but their pricing varies greatly. No matter the cost, though, you’ll never have to worry about running out of space (you can use our chart to compare online storage services).
It’s worth noting that although our top three choices are intended for businesses (check out our guide Best Cloud Storage for Business for a more comprehensive dive), there’s nothing stopping personal users from subscribing. That said, they all come with a minimum user requirement, meaning that it’s better to split the subscription with family members or friends unless you want to eat the whole cost yourself.

Updated Sync.com’s pricing to include its month-by-month cost.
Yes, there is. However, very few cloud storage providers offer unlimited storage space, and those that do don’t offer it on plans intended for personal users. That means that you’re left with either business storage solutions or online backup providers.
You can get unlimited cloud storage by signing up for one of the services mentioned in this list.

What Makes the Best Unlimited Cloud Storage Providers?
Before diving into our criteria and the list itself, here’s a quick glance at our five picks, as well as their most distinguishing characteristics.
- Sync.com for Teams — The best cloud storage; unlimited capacity available
- Dropbox Business — A cloud storage veteran that’s easy to use, but expensive
- Box — Business cloud with unlimited storage and excellent third-party integrations
- OpenDrive — Secure unlimited cloud storage with a great personal plan
- Backblaze — Online backup rather than cloud storage, but the cheapest way to get unlimited storage online.
Since these services all offer unlimited storage space, we’ll evaluate them based on our regular cloud storage criteria.
That includes functionality, meaning things like block-level sync, file-sharing and syncing, versioning policies and collaboration and productivity features. Price is also hugely important, and since most unlimited plans are business plans, that means what you’ll actually end up paying (since they have a minimum user requirement), and not just the listed price per user.
There’s also ease of use, since no one wants a piece of software that’s a chore to handle. Finally, security and privacy are always top of our minds, so we’ll do our best to recommend services that will keep all your data safe as well as private.
The 5 Best Cloud Storage Services With Unlimited Storage
When we say “unlimited,” we mean it in the fullest sense of the word. The main difference is that most of the providers below are regular storage, while one is an online backup provider. With all of this in mind, let’s get started with our number one pick.
1. Sync.com for Teams
More Details About Sync.com:
- Website: sync.com
- Pricing: $15 per user per month, billed annually; minimum of two users
Pros:
- Top-notch security & privacy
- Affordable
- 365-day versioning
- Great file-sharing features
Cons:
- Slower than competitors
- Minimum of two users per subscription
Sync.com has long been Cloudwards’ top choice for cloud storage in general, and with the addition of its unlimited plan in 2021 (refer to our best cloud storage for large files), it should come as no surprise that it’s been catapulted to the top of this list as well. The service features excellent security and privacy, as well as extensive file-sharing functionality and one of the best versioning policies in the business.
It’s not entirely without its flaws, as upload and download times are a bit slower than some of its competition, but this is a small price to pay for everything else Sync.com has to offer its users.
Recover Lost Files With Sync.com’s Rewind Feature
As we briefly mentioned, Sync.com has an incredibly extensive versioning policy. Although it varies depending on the plan you choose, if you’re on the Teams Unlimited plan, you can recover past versions of files and deleted items for a full 365 days.
This means that you can rest easy knowing that if anything gets deleted, changed or overwritten by accident, you’ll have plenty of time to undo what happened. This also offers a great degree of protection against ransomware — a cyberattack that functions by encrypting all your files and demanding a ransom for restored access.
Because you can quickly and easily revert your stored files back to their pre-encrypted state, as long as you don’t wait for a whole year, you don’t even have to consider giving in to cybercriminals’ demands.
Except for Backblaze, which is more of an online backup provider than a cloud storage service (more on that later), Sync.com offers the biggest bang for your buck out of all the entries on this list. Unlimited cloud storage through the Teams Unlimited plan will run you $15 per user per month, which is an incredibly good deal.
Unfortunately, it requires you to sign up a minimum of two users, which raises the cost to $30 per month. You can also opt for the month-by-month cost of $18 per user — again, there’s a minimum of two users. If you want to learn more, check out our full Sync.com for Teams Review.

2. Dropbox Business
More Details About Dropbox Business:
- Website: dropbox.com/business
- Pricing: $20 per user per month; minimum of three users
Pros:
- Incredibly fast transfer speeds
- Lots of third-party integrations
- User-friendly experience
- Smart sync
Cons:
- Expensive
- Privacy concerns
Dropbox was created in 2007 and today it’s one the most recognizable names in technology. It set many trends in both syncing and file sharing, which are still being perfected. Dropbox was the first service to implement the sync-folder model, and its take on it is among the best.
There are two Dropbox plans that offer unlimited cloud storage: Advanced and Enterprise. There’s not much to say about Enterprise, as the details are only revealed once you contact Dropbox’s sales team and ask for a quote. Advanced costs $20 per user per month, but there’s a discount if you pay per year. There’s a minimum of three users though, meaning the least you’ll pay is $60 per month.
When it comes to security, Dropbox has greatly improved over the years. It offers 256-bit AES encryption at rest, 128-bit in-transit encryption, two-factor authentication and even a remote wipe if someone steals your device. You can also choose a data center in Europe to host your data.
However, it’s not zero knowledge; as you can read about in our full Dropbox Business Review, there are some serious privacy concerns with the service.
An Impossibly Fast Cloud Storage Service
Cloudwards has done comprehensive speed tests of all the major cloud storage providers, and Dropbox blows all the competition out of the water in this regard. In fact, it’s faster than should even be theoretically possible, given the amount of data and the connection speed used.
We’re not quite sure how it accomplishes this (we’ve reached out to Dropbox and the company says it don’t compress the files, which leaves us puzzled). The end result is that it’s one of the fastest cloud storage services, thanks to incredibly fast uploads and downloads.
There’s no way around it: Dropbox is expensive. At first glance, $20 per month seems very reasonable, but a three-user minimum shoots this price up to a whopping $60 per month, meaning it’ll cost you more than any other service on this list.
- Price per user, 30-day free trial
- 3TB
- Price per user, 30-day free trial
- 3TB
- Price per user, shared storage, 30-day free trial
- 5TB
- Price per user, 30-day free trial
- 5TB
- Price & storage per user, 30-day free trial. Minimum 3 users (15TB). 1000TB total cap.
- 5TB
3. Box
More Details About Box:
- Website: box.com
- Pricing: $15 per user per month; minimum of three users
Pros:
- Strong security
- Loads of third-party integrations
- 24/7 support
Cons:
- No block-level sync
- Limits on file size
- Expensive
- Zero-knowledge costs extra
Box is aimed exclusively at business clients, which is probably why it’s the only service on this list that offers unlimited file storage on every single one of its plans. Aside from that, it has one of the longest lists of app integrations on the market (more on that later), and also boasts strong security and a very pleasant user experience.
The big caveat to Box’s unlimited cloud storage is that you’re limited by file size. The cheapest plan (Business) will only let you upload files of up to 5GB, with the next tier (Business Plus) limiting you to 15GB.
The Enterprise plan comes with a 50GB file size limit, and there’s also the Enterprise Plus plan, which lets you go up to 150GB. Like most enterprise plans, that one’s only available upon request.
Box’s Slew of Third-Party Integrations
Box integrates natively with Office365 and Google Workspace, meaning you can share and work on documents directly from within Box, as well as collaborate with other people. It doesn’t stop there though, as there’s a long list of applications that you can integrate with Box.
Whether you want to link to files directly in Slack or Zoom, edit PDFs with Adobe or sign documents with DocuSign, there’s a whole lot you can connect to your Box account. The full list features more than 1,500 apps, so you can read our Box review for more details.
Like Dropbox, Box is expensive (see how the two compare in our Dropbox vs Box comparison). The Business plan costs $15 per user per month if you opt for an annual subscription (or $20 with monthly billing), and the Business Plus plan ups this to $25 per user per month annually ($33 on the monthly plan).
Finally, the Enterprise plan is a whopping $35 or $45 per month for an annual and monthly subscription, respectively. You have to sign up at least three users, which effectively triples these prices.

4. OpenDrive
More Details About OpenDrive:
- Website: opendrive.com
- Pricing: 5GB for free; Unlimited storage for $9.95 per month.
Pros:
- Good pricing
- Backup option
- Private encryption
Cons:
- Slow sync speeds
- Occasional sync failures
OpenDrive offers some interesting features, pricing plans and the option to use a shared user account, which is practically unheard of. While that’s great on paper, OpenDrive doesn’t do as well when it comes to execution. Although its security is great and it has zero-knowledge encryption, the user experience feels antiquated and is, quite frankly, ugly.
These usability flaws, as well as its terrible transfer speeds, are the reasons why it’s in fourth place on this list. Although its web interface is adequate, the desktop interface and mobile app are incredibly bare-bones, and the latter tends to crash when under heavy load.
It’s interesting to see a personal plan with unlimited cloud storage, which is what the suitably named Personal plan is. You can even share it among four account users, while the owner manages who has access.
Task Management & Note-Taking
An unusual feature of OpenDrive is that it also offers task management features and a note-taking app. Although these can’t compete with dedicated software like monday.com (on the management side) or Evernote (on the note-taking side), they’re still nifty additions that are nothing to scoff at.
Probably the best thing about OpenDrive is its price. The Personal Unlimited plan is pretty cheap, at just $9.95 per user per month. Additionally, unlike the unlimited business plans we’ve seen so far, it doesn’t have a minimum number of users, meaning it’s a good choice if you don’t have anyone to split the bill with. If all this sounds interesting, read more about it in our OpenDrive review.

5. Backblaze
More Details About Backblaze:
- Website: backblaze.com
- Pricing: $7 per user per month
Pros:
- Inexpensive
- Very easy to use
Cons:
- Lacking cloud storage features
- Flawed zero-knowledge encryption
- Doesn’t offer users much control
Since unlimited storage space is relatively rare among proper cloud storage services, we’re rounding out this list with a backup provider (check out our online backup vs cloud storage guide if you’re not quite clear on the difference).
Because it’s a backup provider rather than a cloud storage service, Backblaze doesn’t offer anywhere near the number of features that the other entries on this list do, with things like file syncing, the ability to share files and collaboration features entirely absent. That said, if all you want is a way to store unlimited files on the cloud, Backblaze lets you do that for an incredibly low price.
Online Backup Made Easy
Backblaze’s greatest weakness, namely its lack of flexibility and features, is also among its greatest strengths. Because there’s very little to tweak in terms of settings and functionality, backing up your data with Backblaze is about as easy as it gets.
Unlike cloud storage, which usually runs all the time, online backup providers like Backblaze let you set up detailed schedules for when to back up files to avoid unwanted traffic on your connection. If this sounds like what you’re looking for, check out our Backblaze review.
As mentioned, Backblaze is very reasonably priced. With unlimited cloud storage for just $7 per month, you’ll be hard pressed to find a better deal anywhere, purely in terms of storage versus cost. If you sign up for a longer period of time, say a full year or two years, it gets even cheaper, with a price tag of $70 and $130, respectively.
- Unlimited GB
Honorable Mention: Internxt Drive
Before we wrap things up, there’s one more unlimited online storage service we’d like to mention: Internxt Drive. It’s pretty new to the field, having launched within the last couple of years.
As you can see in our Internxt review, it still has a long way to go in terms of features. Because of that, as well as the price-point of the unlimited plan, it doesn’t quite earn a spot on the main list.
That said, it does offer unlimited cloud storage in the form of a lifetime plan that costs 999 euros (or roughly $1,150 at the time of writing). This is an incredibly high price tag, and paying that much money for lifetime access to a service that doesn’t have a proven track record of longevity is somewhat sketchy, but it’s nonetheless an option for unlimited cloud storage.
Another interesting thing about Internxt is that it fragments your data into pieces and stores them on servers spread across various European countries. This leads to lower speeds, but it also provides a great degree of security and privacy for your files, as you won’t be putting them all in the same basket.
Final Thoughts: Unlimited Cloud Storage Providers
Well, that’s it, you’ve reached the end of the list. With these cloud services, you don’t have to worry about running out of space on the cloud, no matter how much data you want to upload. Sync.com is undoubtedly the best choice overall, but for those with deep pockets, Dropbox Business is also worth looking into.
What did you think of our list? Do you agree that Sync.com’s Teams Unlimited plan has changed the landscape of unlimited cloud storage? Or do you think one of the other services deserved the top spot? Are there any providers you think we missed? Let us know in the comments below. Thank you for reading.
