SATA ultrabays have a standard SATA connector, which is in the same
physical location as the PATA connector on the older bays - it's not
possible for a single bay to support both PATA and SATA devices. Bear in
mind that the usual use for one of these bays is for optical drives, and
SATA slimline drives have only started appearing recently.
