Western Digital My Book Pro Edition II @ TrustedReviews
 

The Western Digital My Book Pro Edition II is the first external hard drive we've seen that brings RAID and Firewire 800 to the desktop. It's stylish, quiet, and a breeze to use and, if all you want is data security then it's definitely worth considering. However, if you just want a large and fast external hard drive you'd be better served by a single disk solution.
