I may be missing something, but I think there's a problem here.
Even tho Linux treats the drives _as if_ they were SCSI, the
_controller_ is SATA, _not_ SCSI, and so it is not required to
know which disk is closest to the connector, etc. So unless
The SATA controller and connector has that SCSI capability, the
above argument does not hold water.
