When they get native command queueing (NCQ) added in it will start to
make a difference.  Command queueing used to be a SCSI only feature but
real SATA drives have it too.  Most SATA drives so far have been IDE
drives with a SATA interface added, not true SATA drives.  A few new
drives are true SATA though and support the full spec.
