Hi all, I'm planning to get an external FW OWC drive to record audio to. I'm running Logic 8 on a 2.4 C2D Macbook that only has FW400. I'm running a Duet which is also FW400. Is there any reason at all to get the quad-interface drive? I plan to daisy-chain macbook to drive to duet. Should be fine, right? Thanks.
