Hello, I have a 2012 Macbook Pro 13' with a 750gb 5400RPM HDD (non-retina). I am thinking about purchasing a SSD for it, but have a couple of questions. 1.) Does anyone know if this Mac is SATA III compatible, or if it's worth purchasing a SSD if it's only SATA II compatible? 2.) Any recommendations for a SSD thats very fast, and in the range of 200-500gb? 3.) How do I actually replace the drive, while transferring my current data from my current HDD? I've heard everything from involving the optical drive somehow (?), to needing a tray of some sort or a holding thing for the HDD. As you can tell, I'm not a computer person and any help would be greatly appreciated.
