Hopefully this is fairly simple.
I have a HP DL380G5 with a HP Smart Array P400 controller (doing this from memory, not at system). I have the system drives in a Raid 1 configuration using 2-Seagate ST9146803SS drives. It looks like one has failed.
I found a drive locally, ST9146852SS, that seems to be the same other than the rotational speed (specs below).
Is it possible to have two drives in an array that are of different speeds?
