Well i read pretty much everything i could find and yes some success and some failures on the 13 and 17 but the 15 seems to be less of a issue. Not sure here but I ordered the darn thing to try. I already have a OWC 200gb Extreme Pro sitting in the optical bay running the OS today and the spinning drive as backup in the hard drive space which will be removed for the Intel 510 to try and get Sata 3. My game plan open the box install the 510 in hard drive connector space. Boot from the current OS I know i will get initialize the drive which I will do as normal but I will zero it out first than create a partition only maybe 5mgs smaller than the total capacity. This seemed to work for someone. Than I will clone over the OS from the OWC than boot with SMC than pick the new drive and see what gives. just in case I do have 2 OS backups and just did a time machine drive for kicks. I don't normally use time machine Any additional thoughts to those who have had success on the 15 inch. Figured I ask now before I attack tomorrow just in case I am missing some weird little catch to getting this thing to negotiate to sata 3. Thanks in advance.
