TeraBox Review

Having 1TB of free storage sounds too good to be true, especially in the cloud space -- but that’s exactly what one Japanese company is offering. In this TeraBox review, we see whether there’s a price to pay for so much free storage space.

Key Takeaways: What Is TeraBox Cloud Storage & Is It Good to Use?

  • TeraBox has an excellent file management system, allowing quick access to videos, documents and other file types.
  • Having 1TB of free storage space can certainly come in handy, but it’s at the expense of quality features and performance.
  • Though your files are secure, TeraBox isn’t the most private option and lacks client-side or zero-knowledge encryption. 

Top Use-Cases for TeraBox App

  • File size limits: One major limitation on the TeraBox free plan is that you can upload files up to only 4GB in size, which isn’t great if you’re a video creator. 
  • Download speeds: The download speeds were among the slowest we have seen and won’t be suitable for people who need to quickly download files onto their device.
  • Secure file sharing: To its credit, TeraBox offers advanced security features such as password protection and time limits for access to files, even on the free tier.

The Japanese-based cloud storage company TeraBox is making a lot of headlines. Offering 1TB of free storage space, it really is one of a kind. None of the best cloud storage offers anything close to that. However, before you rush to sign up for an account, take the time to read this TeraBox review — all that free data storage may not actually be worth it.

When we first became aware of TeraBox, we were immediately suspicious. Very little is truly free in the tech space. Take Google Drive, for example, which offers plenty of tools but at the price of your data and privacy. Therefore, forgive us for being cautious when we see a company offering enough cloud storage that few users would ever need to pay a penny. 

In this detailed Terabox review, we’ll take a look at some of the potential pitfalls of signing up for an account. We’ll compare the free plan with the paid plan, and uncover whether TeraBox is on a par with the most secure cloud storage services. 

What Is TeraBox & Who Is It For?

TeraBox is a cloud storage service offering 1TB of storage space to free users. This is the most space we’ve seen on a free plan, and the paid tier is one of the cheapest around for 2TB of storage. This makes it ideal for those on a tight budget who want plenty of space to back up photos, videos and other file types.

The Cloudwards Expert Opinion

Dan is a cloud and project management expert with many years experience writing about storage, productivity and collaboration software.

There’s no denying that Terabox’s ample free storage is attractive. However, you can’t view your photos and videos in high resolution on the free plan. TeraBox is also a relatively new service, with no guarantee of longevity like other, more established cloud storage solutions. I would keep this in mind before committing a lot of data to the service. 

TeraBox Pros & Cons

Pros:

  • Solid feature-set
  • Very cheap paid plan
  • Insanely generous free plan
  • Fast speeds on premium plan
  • Now under Japanese ownership
  • User-friendly apps (except for the free plan ads)

Cons:

  • Ads on free account
  • Slow speeds on free plan
  • Security & privacy red flags
  • No zero-knowledge encryption
  • Low-quality playback on free plan
  • Slow or unresponsive customer support

Features: What Can TeraBox Do?

80 % – Good

TeraBox covers most of the bases we look for in a cloud storage service. We’ll break most of them down, but it’s worth noting some of what’s missing. Unlike our favorite cloud storage provider, Sync.com, you can’t create documents with TeraBox. In addition, there are no communication tools like you’ll find with MEGA. 

File Management

terabox file management
We value being able to separate file types, as
it improves access and management.

You can create different folders and subfolders for your files. TeraBox also separates your files into four distinct categories: music, documents, photos and videos. Each tab offers quick access to specific file types; however, you can still access your files via their dedicated folder.

Media Playback

terabox media playback
The media playback works well, but we’re not fans of
the 480p quality limit on the free version.

TeraBox users can view photos, watch videos and listen to music files directly within the web and mobile apps. That’s also where you’ll see the first distinction between the free and paid plans. The service compresses 4K video down to 480p on the free plan. TeraBox also restricts file uploads to 4GB on the free version, which won’t be enough for video creators.

Vault

Terabox personal vault
The personal vault will make it even harder for hackers to access your files,
but in theory TeraBox employees can still access them.

You can protect specific files with two-factor authentication by adding them to your personal vault. Free users can add only 200MB of files to the vault, and paid users can add 2TB. The personal vault works similarly to OneDrive’s vault. It isn’t as robust as IceDrive or pCloud, though, both of which offer a dedicated zero-knowledge encryption folder for your files.

User-Friendliness & Hands-On Testing

75 % – Good

We have few complaints about TeraBox’s functionality. However, there’s no denying that the pop-up advertisements reduce the quality of the overall user experience. That’s the real price you pay for the free storage space. If you want to make TeraBox your daily driver, we recommend jumping on the paid plan to ensure you don’t pull your hair out in frustration.

How to Install TeraBox

We’ll take you through the steps to installing TeraBox so you can use it on your desktop. Note that this process is for macOS. Windows users can access the app via the Microsoft app store.

  1. Access the App store

    When you arrive at the Apple app store, search for “TeraBox: 1024GB cloud storage.”

TeraBox on Desktop: macOS & Windows Apps

Terabox desktop
The desktop app has snappy performance, with a design
that mirrors the clean aesthetic of the web variant. 

You can download Terabox via the Apple or Microsoft app store. The apps are a mirror image of the web version. Unlike other desktop apps, there’s no dedicated sync folder, nor can you run automated backups. Instead, you’re limited to the same experience as with the web browser.

TeraBox on Mobile: Android & iOS Apps

Terabox mobile
Free users can’t skip past pop-up ads, which makes
using the mobile app rather annoying.

The user experience on the mobile app depends on your plan. Free users will have third-party ads pop up in a range of formats, including video, which you can’t skip. In terms of functionality, you can update photos and videos automatically, access your files and share them with other users. The UI is a little messy, but it’s usable. 

TeraBox Pricing: How Much Does TeraBox Cost?

95 % – Excellent

TeraBox offers only two plans: free and Premium. The paid plan gets you 2TB of storage. Compared to other platforms offering the same amount of storage, the paid plan is extremely cheap at just per month and removes many of the pain points of the free version.

TeraBox Free Cloud Storage Plan

You know by now that the free version gets you a ton of storage space. Beyond annoying ads and compressed media quality, there are other limitations worth noting. You have only 10 days to restore deleted files, downloads are limited to one file at a time and TeraBox throttles download speeds significantly (see our speed test results below). 

Outside of the major talking point — the storage space — TeraBox isn’t one of our favorite free options. If you don’t need that much space, we recommend looking at the best free cloud storage to find an alternative.

Pricing Plan Breakdown

You have a few payment options on the Premium plan — monthly or yearly. You can also choose to auto renew or pay manually each time your subscription ends. The best value is on the annual auto-renew plan, which gives you 2TB and lifts restrictions found on the free plan, all for as little as per month on annual billing. That’s a great value.

TeraBox Speed

85 % – Very Good

We ran some in-house tests to see how well TeraBox does with upload and download speeds. Using an internet connection of 100 Mbps, we uploaded a 5GB folder that we filled with a range of file types. This time around, we had to test both TeraBox plans, as the company slows down speeds for free users.

Notes From the Lab: Our Detailed Speed Analysis

Our lab tests showed that both plans were stable and consistent during uploads, with very low CPU usage, and the same was true for downloads. File downloads were limited to five at a time, but all in all, this is good work from TeraBox, as long as you only look at the premium plan numbers.

When it comes to the free plan performance, you’ll definitely feel the speed difference on the free plan, especially for downloads. Upload speeds were only a bit slower, but free downloads took more than five times as long as the premium downloads.

Security: Is TeraBox Safe?

40 % – Terrible

We spent time researching TeraBox’s security measures to see if it has robust security protocols. We’ll take you through our findings below.

TeraBox Security Features

TeraBox’s security features are decent. The vault offers an extra layer of protection, as you use 2FA to access files. Remember, it’s limited to 200MB of space on the free version. Users have the option to password-protect shared files, and you can set time limits for access to shared links. Unlike other platforms, you can’t limit the number of file downloads. 

Detailed Security Analysis: Encryption & Cloud Security

TeraBox uses TLS/SSL encryption to protect users’ data in transit. These encryption protocols are tried and tested, and they do a fine job of keeping your data safe when uploading files to TeraBox’s servers. 

It’s unclear what protocol TeraBox uses to protect your data at rest. We reached out to them on two separate occasions to get a clear answer. Sadly, we didn’t receive a response the first time and on the second occasion we received a generic response that didn’t explain exactly what encryption is in place. The lack of transparency is alarming.

Although it’s reasonably safe to assume that Terabox uses something like AES encryption for files at rest, the combination of an unusual amount of free storage and a lack of forthrightness about how files are protected makes us suspect that there might be corners being cut on the security front, which is why we scored Terabox so low in this round.

Privacy: Is TeraBox Private?

50 % – Poor

There’s a lot of confusion surrounding TeraBox and privacy. Many still believe it’s owned by a company based in China, a country known for its lax approach to privacy. However, it’s actually in the hands of a company based in Japan, which has a better track record of managing user data.

Zero-Knowledge Encryption

TeraBox doesn’t offer zero-knowledge encryption on any of its accounts. In theory, this means the company can scan your data. The company doesn’t explicitly say it does scan data, but that’s not to say they’re being honest. Keep that in mind before uploading your files.

TeraBox Privacy Policy

The privacy policy isn’t the easiest read. It’s almost 5000 words long and written in small font, which we believe is by design as a deterrent for people reading. For comparison, Sync.com’s privacy policy is nicely formatted and less than 2000 words in length – this suggests openness and transparency. 

Digging into the Terabox’s policy, there were certain points that particularly stood out. For example, the company states it can share your data if they’re legally asked to do so. This isn’t great, but it’s not unique to them.

However, one glaring point worth sharing is that Terabox will share your data if it’s “necessary to publish news, carry out supervision by public opinion, and so on in the public interest.”. It doesn’t, however, share in what situation that would be, nor did they respond to our request for them to clarify. Either way, it’s a red flag.

The company also shares your data with its affiliates; that’s your name, email address and telephone numbers. The affiliates are able to “promote services” – which is company speak for sending marketing and ads to you.

There’s a lot of vagueness through the privacy policy, and the lack of zero-knowledge encryption leads us to suggest privacy focused consumers look elsewhere. 

TeraBox Customer Support

20 % – Terrible
Terabox support
Due to poor customer service, TeraBox won’t win any awards for its user support system.

TereBox’s customer support is shockingly bad. There’s no telephone support, and finding ways to contact the company directly is a mess. There’s a very basic help center for common issues, and you can access ticket support once you find it.

Email Support Speed & Quality

We contacted TeraBox to find concrete information on whether it scans user files and which security protocols are in place. We were given a response time of 24-48 hours. 

Unfortunately, we never received a response for  our first query, and the second time we reached out we got a generic vague response that didn’t answer our question. This is telling, as a company that’s not transparent about its access to user data is a huge red flag.

TeraBox vs Other Cloud Storage Services

Let’s look at how TeraBox stands up against some similar services. We’ve intentionally included solutions with a generous free tier, and we’ll compare their features beyond just the available storage space.

TeraBox vs Dropbox

As far as free storage space goes, Dropbox is terrible, offering only 2GB. That said, it doesn’t throttle speeds on the free plan, though it’s not the fastest cloud storage either. Dropbox is also a better option for productivity thanks to Dropbox Paper. We’re equally as cautious as with TeraBox on the privacy front, though — learn why in our Dropbox review.

TeraBox vs Google Drive

Google Drive’s free tier offers 15GB of storage space. It doesn’t reduce playback quality, and it takes the upper edge with its productivity suite. TeraBox has more widely accessible security features, though, as Google Drive doesn’t offer password protection or file access limits on most of its plans. Learn more in our Google Drive review.

TeraBox vs MEGA

MEGA offers 20GB of free storage up front, plus an extra 10GB for one year if you install MEGA’s applications and 5GB for every referral. The key difference is that MEGA offers zero-knowledge encryption, so your files are as private as they come. Though it has a user-friendly interface, we feel TeraBox offers a more modern design. To learn more, check out our MEGA review.

Community Feedback: TeraBox Reviews on Reddit, Quora & Social Media

Most users online are concerned about the safety of their files with TeraBox. However, in a post on Quora, one user wrote, “It seems that there is no intention of stealing, because the parent company of this software is in Japan, a country known for its strict data security for enterprises…”

For performance, one user on Reddit complained that upload and down speeds didn’t improve when they upgraded to Premium. Of course, this is just one person’s experience — in fact, we had the opposite experience during our in-house testing.

The Verdict: Is TeraBox Worth It?

TeraBox isn’t a scam, and there’s nothing in its privacy approach that stands out as worse than the likes of Google Drive and Dropbox. You get a subpar product with the free plan, though, especially in terms of speed and playback features. The ads are also a pain and vastly reduce the user experience. For us, 1TB of free space doesn’t make up for all of that.

The Premium plan does bring improvements, and for less privacy-focused users it’s a good option considering the affordable pricing. There are other cheap options available, though, and they come with better privacy standards and more productivity tools. You can check them out in our selection of the best cheap cloud storage.

What’s your verdict on TeraBox? Is the free tier worth the inferior features? Is there another storage solution you would recommend as an alternative? Let us know in the comments. Thanks for reading.
