Thing with IBM HDs, in my experience, is that some are good from the
start, some are bad from the start. When I was building a big array a
while ago using IBM 120GXP HDs, out of 8 per server, 2 or 3 failed, but
they failed almost straight away (clicking sound). The rest have run
pretty much flawlessly till today.

IBM HDs are well-known for having the best RAID performance, due to the
firmware being tuned that way. Check out storagereview.com and you'll see
what I mean. Individually they don't perform much better than the
competition, but in a RAID setup they actually perform better. Not sure
why as I'd assume high speed independent HDs would lead to high speed
RAID... but anyway, IBM HDs are best for RAID from the performance results
for some reason.
