I wanted to upgrade my hard drive on my 2011(I think, it was the first one with thunderbolt) MBP and I currently have a 500GB internal drive, I wanted to upgrade to a 1TB and preferably a 7200 rpm one (if that is possible on a 2.5" drive without it overheating my laptop). I also was thinking of removing my optical drive and putting in a second Solid State HDD for quick speed for when I need to run video editing software. via the OWC Data Doubler Kit http://eshop.macsales.com/item/OWC/DDMBS6E120/ does anyone have any tips or warnings for doing this? which drive should I run my OS off of? What is the best way to copy my current hard drive onto the new one? and on a related but somewhat off topic note, I was looking to take my now spare 500GB hard drive and upgrade my PS3 hard drive, has anyone done anything like that before? backup process? suggestions?
