This topic seems to come up pretty often, but usually in the context of another thread. I'm just getting started with Logic, recording at most 2 tracks at a time through a firewire interface. Will probably end up working on projects with at most a dozen tracks or so, some of them MIDI but mostly recorded audio. I've been looking for an external drive on which to record my projects. I'm looking at 500GB drives, both of them have FW800 (wouldn't need to daisy chain with my FW interface), one is a desktop drive at 7200rpm, the other is a bus powered drive at 5400rpm. Bus powered is attractive to me, reducing clutter on a crowded work space (one less plug!) and the portability is also attractive. Is it a bad call to go with a 5400rpm drive though? I'm guessing the speed of FW800 is bottle necked when it hits the drive itself. The drives in question are a Western Digital Passport (portable, 5400rpm, FW800) and a Seagate Freeagent Desktop (7200rpm, fw800). Both 500gb, both about the same price. Thanks for your input!
