Bitcasa Review

April 2016: Bitcasa Drive has been discontinued.

Bitcasa.  Infinite storage.  Infinite backups.  180 day file version history.  Access your data from any device.  Sound too good to be true?  It sure sounded that way to me.  For $100 a month, you can have an unlimited amount of space in the cloud.  Bitcasa also offers a whopping 1TB of space for only $10/month, beating out most competitors.

  • Unlimited storage space; backup your entire hard drive to the cloud
  • 180 days of file versions
  • Fast file uploads
  • Apps for Android, iOS, and Windows


  • 5 device limit
  • Security could be better (there’s no option to use a personal encryption key)

The Bottom Line

Bitcasa delivers on its promises, and if the business model holds up, this could be the Dropbox killer we’ve been waiting for.

Infinite Plan:

  • $99 per month
  • Unlimited storage

First Impressions: Simple, Easy-to-Use Interface

By default, files stored in Bitcasa don’t use any space on your computer; they’re all stored in the cloud.  This is unlike Dropbox and other services, which also store a local copy of files.

You can store files in both locations by choosing to “mirror” folders.  This will keep local copies, while also mirroring them to the cloud.

Bitcasa: Setup mirroring of your files

Bitcasa can mirror all your files to the cloud.

Your Bitcasa drive is accessible from the desktop, system tray, and Windows Explorer.

Bitcasa's 8 exabyte drive

The Bitcasa drive. Good luck filling up 8 billion gigabytes.

I liked how minimalist the interface was.  There’s no GUI (only a settings box).  Most Bitcasa actions can be performed from the right-click context menu, such as:

  • Send a file to a friend
  • Copy a file to Bitcasa
  • Mirror a folder to Bitcasa
  • Stop mirroring a folder

No Limits

I’m wary of any service that advertises “unlimited” storage, only to throttle your connection down to unusable levels after a certain amount of GB have been transferred.

Let it be known: Bitcasa is the real deal.

I uploaded a whopping 700 GB without any noticeable slowness.

Web Interface

The Bitcasa web interface is where you access your files, and restore older versions of files.

Bitcasa can also display thumbnails of camera RAW files – making this a great service for the professional photographer.

Infinite Versions

Any old, changed, or deleted files will be kept on Bitcasa – apparently forever, according to their support department.  This breaks from the standard “30 day history” common with other online backup services.  Bitcasa has an unlimited file version history.

Bitcasa Android app

Bitcasa comes with sleek, well-designed apps.

Mobile Apps

Bitcasa has apps for the most popular mobile devices.

  • Android
  • iOS
  • Windows Phone (Metro)

The apps have the same functionality as the desktop application.  You can upload, share, backup (on Android), and view all your files.


Bitcasa is fast; it maxed out my upload speed at 7.4 megabits per second (Mbps), and remained at that speed for all 700 gigabytes of my test files.

Download (restore) speeds were also fast – about 23.4 Mbps, although it did not max out my internet connection (34 Mbps).


Bitcasa encrypts all files before transfer being transferred, and all files are stored encrypted.  It also stores at least 3 copies of files on their servers.

Bitcasa has come under fire for their choice of encryption.  It uses convergent encryption, which derives the key from the file itself.  This means identical files encrypted on two different computers will result in identical encrypted files.  This enables Bitcasa to de-duplicate data and offer infinite storage, since only 1 instance of a file is stored (even for multiple customers).

The downside to this is that an attacker could “know” the contents of a file if they also have a copy of the file.  Although this isn’t a problem for family photos and other personal documents, it could be used to discover copyrighted works like MP3s (which aren’t unique) or banned books, for instance.


Update Nov 2014: For the personal plans, Bitcasa apparently only provides support through their community forums now.

Bitcasa provides a variety of support options:

  • Live chat
  • Email
  • Documentation
  • Searchable knowledge base
  • Community forums

I was blown away by their live support, there’s very little wait time and I got instant solutions to problems (thanks, AJ!).


Bitcasa is a game changer – a service which all new cloud storage services will be judged by.  It combines cloud storage, sharing, and backup features with huge amounts of space.
