I'm pretty sure *all* SAS controllers can be attached to SATA
drives. If I understand correctly, SAS is a superset of SATA.

Well to be fair, IDE didn't exactly replace
SCSI. ;) And,
interestingly, it's starting to look like SCSI drives will still be
produced after IDE drives are no longer being made.
Also bear in mind -- the USB Mass Storage protocol stack is
essentially a USB wrapper for the SCSI command set. SCSI is going to
leave its mark for a long time to come. Heck, ATAPI (usually used for
CD/DVD drive interfacing) is basically "SCSI over ATA"...
SATA is PATA-over-serial-link, so I guess that makes ATAPI+SATA
SCSI-over-PATA-over-serial-link. Layers, so many layers...
