The problem with Firewire is that you need
 a) a "good" chip in the controller
 b) a "good" chip in the Firewire-to-SATA controller in the external 
unit (there are no native firewire disks...)

That's what makes IEEE1394 always a bit of a gamble.

There's a reason someone came up with this eSATA stuff...
