Looking at investing into an external for my MBP. Anyone have one (or at least know of a brand) that they're fond of? Has to be available on Amazon as well (giftcard). To be more specific, I'm looking for these specs: BUS Powered USB AND FireWire compatible 750GB - 1TB Memory The ability to power it with an adaptor* (optional requirement and the adaptor doesn't have to be included) Backing up my files via Time Machine and storage of my music is the only thing it will be used for. 95% of what I use my computer for is music related (creation, live sets, etc.); also, the specs of my laptop are in my signature if it is of any relevance.
