On the most basic level I think of SAS as basically the new
SCSI, and SATA II as the new PATA.
SCSI = smaller, faster
SATA II = bigger, slower
SAS drives typically have higher quality control on them too. I
get the impression that a lot more firmware bugs get out on the
SATA drives vs the SAS/FC drives. Though the only time I've ever
had to upgrade the firmware on a disk drive was regular U320 SCSI
disks from Seagate sold via Dell.
