My brother just got a 2012 13" MBP today, I installed a new Vertex 4 256GB SSD in it. This thing is insanely fast, faster than my rMBP SSD. Here are some screens of the SSD speeds using Magic Disk Speed App. The SSD has the latest 1.5 firmware. I have always liked OCZ SSDs, Ive owned 5 different OCZ SSDs myself with no issues, ever. I highly recommend OCZ SSDs, even though people say they are unreliable, I myself have never had issues with any of the OCZ SSDs Ive owned. I highly recommend the OCZ Vertex 4 SSD for anyone looking for an insanely fast SSD.
