so im looking to do the optical bay swap in my new MBP, when i get it in two weeks LOL. originally i was going to put the SSD in the optical bay, but iv read stories about 6gbps not working, so im going to put the SSD in the main bay and the HDD in the optical bay. now iv read that the SMS sensor on the macbook does not work for the optical bay. im looking at the Samsung Pinpoint M8 1TB 5400RPM HDD because i read it was actually faster than most 500gb 7200 rpm drives. but i cant find out anywhere if the thing has a SMS or G sensor built into it, or if it needs one for that matter.
