From their lit (the Lacie 250):
Available with high-speed FireWire interface, the LaCie Hard Drive offers fast data transfer rates (up to 400Mbits/s) that are required for substantial jobs like rendering 2D/3D images
I find that utterly humourous - for anyone that has done any 3D rendering - you realize the rendering engine spits out one frame (about a meg) every say 30 seconds to 30 minutes, which means you need something capable of about 0.25-16 (not 400) Mbits/s.
Uncompressed CD audio requires about 10MB a minute (or about 1.5mbits per second) so I'd say you're pretty much covered.
