Drive mechanics _can_ and _do_ match on the "commodity" ATA and SCSI
drives.  You're essentially paying more for the SCSI target logic.

However, there are not many "enterprise" capacity/spindle (18-146GB,
10-15K rpm) drives available in ATA.  That's because most people don't
want to pay the kind of money for an "enterprise" set of mechanics (let
alone reduced capacity).

Western Digital and a few others do offer 73GB, 10K rpm drives in SATA
-- basically coming off the same line as the SCSI, FC and SAS versions.
