because they are always finding new ways to make them cheaper.

I once had 2 hard drives fail simultaneously in a Dell PERC 3/Di RAID 5
array but I think the RAID controller was confused and failed 1 drive
completely and kept the actual failed drive online. I suspected that the
drive that was off-lined probably didn't have any problems at all. Dell
replaced both drives without question and I simply updated the firmware
on the controller and set up the RAID arrays all over again (backups are
always your friend).

I long ago stopped using consumer grade anything for servers since the
server grade hardware is cheap enough and I feel that I can adequately
lay the blame for failure at someone else's feet.
