Do you have an early 11' mbp? Why don't you go under system profiler and determine the link speed. From there you should be able to check to see if it worked or not.
I have an early 11' 17" and have Sata III on both bays.
So you haven't installed the update?
i did but i don't have an sata iii drive on my optical slot to test. hence the whole reason why i'm asking the forum if anyone's been able to test it.
are you trying to be annoying?
