Sata III HDDs sustained throughput is the same for being on a sata II or a sata III port. Ther is ONLY one parameter that is improved by being on a Sata III port, and that is the very short burst speed.

Case inpoint compare the Sata II samsung F3 on a sata II port and a Sata III WD Black on a sata III port, Bet you would not be able to tell which is which in real day-2-day usage.
Note I have both of the above configurations.
