I just got a 27-inch iMac (mid-2011) and updated the EFI firmware as prompted. It shows the SATA port for the SATA to be 6 Gigabit, but the "negotiated link speed" to be 3 Gigabit on that drive.

Why?

Some suggested resetting SMC (just unplugging the iMac for half a min, then plugging back in). I did - no dice.

Surely this should be running at 6 Gigabit, right?

I have the 256GB SSD as spec'ed in the online Apple Store. (Also have a 2TB HD internal.)

maybe because apples SSD is still SATA II and not SATA III
 
Wow, that's surprising and rather disappointing. I have an Intel 510 sitting on the shelf. If I swapped it in for Apple's, I am guessing it would perform significantly faster.

Most unfortunate.
