Hey, I ordered the MBP 15 hi-Res glossy, 2.3 ghz, 128 GB Apple SSD and need to upgrade it to 8 GB ram and a new SSD. Will do the optibay trick and have 2 SSD drives in the MBP. But have been hearing quite a bit different stories from MBP owners. For some the vertex 3 works, for some not. For some intel 510 works, for some not. For some crucial m4 works, for some not. Does anyone have trouble with the SATA II based Intel 320 SSD ? What SSD works in a MBP 2011 ?
