My Dell laptop has only 1 firewire connection, and I need both a soundcard and an external hard drive. Which is better: 1) Firebox on my firewire connection, external hard drive on a USB port? 2) External hard drive on my firewire connection, Mbox on my USB port? I'm new to recording and am trying to head off issues down the road, so any and all opinions would be welcome. Thanks.
