It's RAID for dummies, but way better -- finally, a consumer-friendly, infinitely expandable redundant backup system that requires very little configuration or maintenance. It keeps track of your data and constantly backs it up across all available drives, so even if one goes down, you never lose anything -- and actively warns you when your space is filling up, or when a drive needs replacing.
For those of you with a lot of stuff to backup (I have three laptops, a desktop, and gigs of archived video projects), it means no more adding yet another mis-matched external drive, no more taking up yet another USB port or crowding your power outlets with yet another bulky AC adapter each time you need more storage -- just hot-swap new internal drives into Drobo whenever you need more space. Quick and easy!
Be sure to watch the demo video to see it in action, or check out this review for a full description of why it's such a clever replacement for the typical consumer-grade external hard drive.
