That can't be true; I've seen SATA disks, and they use too few wires to
be even vaguely SCSI.

Or were you speaking just in terms of the command and response packets
and the protocol formed thereby?  Saying that SAS is SCSI because of
that is like saying that an airplane is an automobile because they both
move passengers and freight: true as far as it goes, but the
differences in the layers underneath are so huge as to swamp the
similarities for almost all purposes.
