Macbook Pro ssd setup

Checked some of the reviews and other buyers have reported that it will work at sata III speeds.

 

The 2012 15 MBP will work with SATA 3 in optical bay. For the caddy, go for the generic one.

 

Sorry this was intended for loneranger93.. or maxwelltech

Hey loneranger93, im just wondering how this worked out for you as i have the same exact system you have. I bought the Drive caddy on amazon and a Kingston 128 SSd and first put it into an external drive, formatted it, installed mountain lion, booted up from mountain lion from external drive and it work flawlessly. I went on to install the actual Hdd into the caddy and replace the optical bay. After all was back together it booted up perfect and FAST, until i rebooted it to check boot speed, after that i got the spinning beach ball and it would hang and freeze all the time not even useable. i must have reformatted and re installed 7 times. after hours and hours of research i came to the conclusion sata 3 will not work in this laptop (Lots of people saying this on threads with a google search) so i gave it up and returned it back to staples.
So im wondering if this worked for you? I would like to try the samsung if it did.
Thanks!

 

ill try it and tell u. i still ddidnt get my laptop.
