We have a fair number of SAS 3.5" drives, and yes, 10k or 15k speeds.
those are internally 2.5" disks in a 3.5" frame. you can't spin a 3.5"

Sorry, that's incorrect. I have, sitting here in front of me, a
Dell-branded Seagate Cheetah, 600GB (it's a few years old) 15k 3.5" drive.
if you take one of those apart, you will find ~63mm (2.5") disk platters
inside, and an identical mechanism to the 2.5" 600GB 15000 rpm drive of
the same generation, just sitting in a larger frame.
