The company’s pitch is simple: You give them $99 per year, they give you infinite storage space online. The deal is currently being offered for $69, which comes out to $5.75 a month. That’s it. No capacity limits. No additional charge for certain file types or for web/smartphones. File version history? Infinite. Want backup and mirroring of existing data? You can get that, too. Bitcasa promises an online drive that seamlessly integrated with Windows Explorer, giving you all the benefits of local storage for substantially less money. That was enough to pique ExtremeTech's curiosity, and to take the service for a spin. What it found was a genuinely interesting and valuable service, but there are a lot of bugs that need to be ironed out before you should recommend it to your friends and family."
