jdiaz9 Posted May 6, 2013 Share Posted May 6, 2013 Hello, Recently acquired a Corsair Force GT 120 GB SSD for my MacBook Pro (5,2) and I am having an issue with it performing at SATA I speeds. I am aware of the issue with the nvidia sata controller and I have been browsing for 2 hours now without a solution. Everything I have come across is about a year old so I was wondering if a solution or some update from corsair has come about that I am not aware of. As of now I am running the latest: Corsair Firmware: 5.05 Mac OS X 10.8.3 This negotiated link speed being at 1.5 gigabit is annoying. I have tried resetting the SMC, PRAM, reinstalling OS X, disconnecting the CD/DVD drive, and no help. Anything suggestions? Link to comment Share on other sites More sharing options...

jdiaz9 Posted May 7, 2013 Author Share Posted May 7, 2013 Hello all, So after looking around online without a solution I was forced to think for myself. I came up with an idea where I would switch the location of the SSD with that of the CD/DVD SATA cable. I acquired an OptiBay or DataDoubler type of add on and installed the SSD in the CD drive bay area. I then switched the original 7200 rpm drive over to the original location as a spare data drive and booted the MacBook. To be honest I didnt think that solution would work, but I figured I'd give it a try. Anyway, I went to the system info app under about this mac and checked the negotiated link. To my surprise it displayed a negotiated link of 3 gigabit. I ran a speed test (blackmagic) and I got speeds higher than SATA I (150.5 write, 258.2 read) so I knew it had worked. I don't how and I don't know why this worked but I figured I would share my solution with the world. Also, rebooting doesn't seem to change the negotiated link speed and it has remained at 3 gigabits for quite a while now. TRIM has been enabled and I am off to enjoy my SSD. Thanks. Oh yeah, please note that I am running OS X 10.8.3 and SSD Firmware 5.05 (updated with windows). - Javier Link to comment Share on other sites More sharing options...
