Thanks for the comments.

It was really protocol/bus behaviour differences (if any), between SATA 
drives in a SAS environment, vs SAS drives, that I am looking at.

I do know that SATA drives only support a subset of the SCSI commands 
and wondered if the SAS drives were more "clever" in a multi drive scenario.

The comment I saw, which I'm trying to verify, mentioned the SATA drives 
"held the bus" or similar longer than SAS ones.

Regards,

Richard
