As far as i know SAS is a faster version of SCSI! But for more info, have a look at this:

It's not about speed. It replaces parallel SCSI with serial attached devices.

I came to conclude that from this statement!

SAS is a performance improvement over traditional SCSI because SAS enables multiple devices (up to 128) of different sizes and types to be connected simultaneously with thinner and longer cables; its full-duplex signal transmission supports 3.0Gb/s.
