I don't believe anybody makes them yet. Beware of bits and bytes! 1394a is 400Mbits/sec or about 50MBytes/s. My fastest FW drive can sustain about 35MB/s so I'm not sure where your 7800KB/s figure comes from?

I know that ide transfers data at 7800 KB/S and firewire moves it at 400 mbs. What I want to know is, How much more will I pay for a true Firewire CD-RW? Is there such a thing? Who makes them?
