I very often hear SAS hard drives referred to as "6Gb/S".
However, when looking at actual specifications, the top benchmarks are in the 100s of MB/s.
Right here, the spec for the Seagate Cheetah states Interface: 6-Gb/s SAS.
What is the difference here?

6Gbit/s is the SAS interface speed, and not the actual harddrive speed (which is in the 100s of MBytes/s range, and that only if you are measuring the sequential transfer speed)
