Drobo - Data Storage Robot
I haven't tried this myself, but it looks promising. It's a self-managing, self-contained RAID drive. Just plug this fella into your computer and copy your files over. Drobo will automotically backup your data. No worries. (Well, so long as you trust a robot to give your data back to you. I can see it now, "I'm sorry, Dave. I can't do that" ;o)
Incredibly easy to set up and use. Plus, it looks fantastic sitting on my desk. I love my Drobo!
Best, and most attractive harddrive storage out there. It's a simple little home server.
Looks pretty promising
