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
