Probably for the same reasons people buy VelociRaptors? From what I can see, the WD Xe is just the enterprise SAS 6Gb/s version of the VelociRaptor. Plus, it's 2.5" so you can pack them pretty densely. I remember seeing the 1U (or maybe 2U?) server in the office and it holds 8 2.5" drives. Practically inaudible, too.
Seriously, though, unless you need to run like 24 of these in a 4U case with hotswap or something for a 24/7 RAID array, I wouldn't bother. Besides, I'm not even sure if you can use SAS drives on regular SATA controllers. SATA drives on SAS controller yes but I don't think you can do it the other way around.Edited by rui-no-onna - 6/22/13 at 2:25am
