Has anyone had success with using a OCZ Vertex 3 with a MBP 13" Mid 2009? Recently my hard drive failed so I purchased a 120GB OCZ Vertex 3 to replace it. I installed the drive and operating system however there were lag issues and sometimes the computer would freeze entirely. Also at times it would be unable to start up and only have a ? folder appear. I took my laptop to the Genius Bar and they said my Macbook Pro was not designed to take SSD and was having comparability issues with the drive. Sometimes the drive was there, sometimes it wasn't. However, I thought a drive was a drive in this case, as long as it was right connector. (I am aware that it is SATA III and my laptop only supports SATA II) What are your guys' thoughts? Is there compatibility issue with SSDs and the 2009 Macbook Pro model?
