Hello, I just got my new imac 3.06 - 21.5 with the upgraded graphics card. I installed Final Cut Studio and I'm looking at getting an external hard drive to use as a scratch disc. Has anyone used the Voyager Q Quad Interface FireWire 800/400/USB 2.0/eSATA hard drive dock? I think this is a great idea because I can swap out drives as I work on them. Any comments or reviews would be great.
