Actually it's perfect for a home user or a self employed 'creative' type. You buy one, feed it disks and forget about, it protects your data without you even needing to know what RAID is. Run out of space, pull out a disk and feed it a bigger one. No pressing buttons, no configuring, no understanding needed.
It's the best consumer storage product I've yet seen, it's obscenely simple!
This seems to sum up the product from what I've read. I think I may have to take the plunge.
