The SAS disk are a little faster than the SCSI ones, but you only got 6 arms in

The integrated SAS controller on the M25 can attach 1 "EXP 12S" (12 drive SAS expansion). Write cache is required.

This should get you plenty of arms, but the question becomes what's the disk request limit for the internal controller ?

There's also a dual SAS controller that can attach multiple EXP 12S drawers.
