LaCie drives (Score 1)

Check those out - their mobile hard-drives come in USB 2.0 and FW/USB2.0 flavors. I own a USB2.0 drive, but I saw the FW model in my local Apple store - looks identical, utilises 6-pin cable, light and gorgeous.

Also, on their web-page you can find all the dimensions and other specs - check it out, highly recommend.
