Hmm, yes, but I've often wondered if there -really- is a difference between
"desktop hardware" and "server hardware" - and that maybe they are designed
for different MTBF? I. e. a "server grade" HDD will last longer if not
regularly turned on and off, while a "desktop grade" HDD will die quicker
if never turned off?
