Hi all, I've been poking around the threads looking at the discussions around 5400RPM vs 7200RPM and price and size and brands and.... What I'm really wondering is, for a MacBook Pro user (new college student) who will be doing video capture, which is the best portable drive? Overall, I've learned that the small, portable drives only go up to about 160Gig and that a desktop model with 500 Gig runs about the same price (which is a reason to get a desktop model). But if I really need portability, what specs should I look at (or avoid). For example, should I choose FireWire over USB? 7200 RPM over 5400 RPM? Or does none of that really matter and I can pick price/Gig? Thanks!!
