Had a look at the wikipedia, usually a good start for this sort of thing
http://en.wikipedia.org/wiki/SATA
Interestingly it seems SATA II is the name of a standards body, not a
standard http://www.sata-io.org/namingguidelines.asp
The following is very interesting, as it would seem to apply to all SAS
adapters, potentially:
How does SAS compare to other serial technologies, like SATA?
Serial Attached SCSI is an ideal I/O interface for server storage
applications. *The SAS protocol supports SAS disk devices and also
includes support for the Serial ATA II protocol [!] and command set*,
offering customers the flexibility to directly connect both high
performance SAS disk drives and high capacity low cost SATA disk
drives to the same SAS controller. This added flexibility makes it
easy for companies to standardize on a single I/O infrastructure for
both mission critical storage and secondary storage dependent solely
upon the disk drives installed. Customers can standardize on a single
I/O controller or storage system for all of their storage
configurations reducing training and repair costs.

So it sounds like the specifiers of SAS made SATA 3Gb/s a subset. If
that's so, I guess a SATA drive can be treated as a (less sophisticated)
SAS drive.
