Hello all, I'm getting a new mbp (non retina) with a 7200 rpm internal hd. I'm coming from a desktop world where I had tons of storage for video and motion graphics projects. So, I'm on the lookout for external drives to expand my storage space. What is the fastest option for me to look for? I'd also like it if the hd doesn't need to be plugged into the wall and can be powered by whatever port I connect it to? Minimal space I'm looking for is 1tb (I'll buy multiple), but would be open to 2-3tb options if they exist! Thanks all.
