What do you think is the best external hard drive and enclosure? I am looking to possibly pick one up for my MBP but can't really decide. I am assuming anything with a firewire connection will do seeing as Thunderbolt isn't an option at this point. I really don't care whether or not it's a 2.5" or 3.5" unless there is a reason I should choose one over the other. I am almost leaning towards a 2.5" because it's smaller and most likely quieter.
