The actual SAS run at 6Gb/s with a 10b8b encoding, delivering 600MB/s per link, and susual SAS hard-drive or SSD supporting two bi-directionnal links, SAS offers 1.2GB/s bandwidth since years (this is 20% more than Thunderbolt).
The new SAS 12GB/s will offers up to 2.4GB/s per peripheral in 2013, and the bests SAS RAID controllers will be able to provide 16GB/s, the equivalent of 16 Thunderbolt ports! This is a breakthrough for SSD storage systems.
