Yes, SATA did away with the whole master/slave thing specifically due to the
performance hit you take with multiple drives on the same bus. ATA/IDE can
only talk to a single drive at a time which means another drive with pending
operations must wait for it's turn to talk to the cpu/system etc.
SCSI on the otherhand supports communicating with multiple drives
concurrently.
