Okay so I bought my rMBP with the intentions of putting a new SSD in it and using the stock drive in an external housing to use as a place to store my music and movies and use on occasion. Well, i wasn't aware you can't swap out the SSD on the newest rMBP yet, oh well. Ill buy an external, problem solved. Now the question, which one to get lol. Do the SSDs that don't work as an internal work as an external? cuz some of those larger replacement drives would make nice external drives. I just don't want something to go wrong and hurt either the external or my laptop. Ive got about 500 to spend and would like to be as close to 1T as possible obviously. Suggestions?
