I’ve got a later model 5160 with an IBM WD25, and it’s knocking on heaven’s door. I assume that this massive full height drive with 4 platters uses a lot of power, but I cannot find any specs. Has anyone ran dual HDDs in a 5160? I’ve got a few ST-251 I could put in it. I know the 5170 specifically talks about two drives, so I assume it’s PSU is up to the task, but the 5160 is about 60 watts less.
