Firewire makes a really nice hot-pluggable I/O bus which works nicely  
with external devices.  Your typical external Firewire drive is  
generally a medium-decent IDE drive (ie, one with a 3-year warranty  
and more cache than the typical drive sold today) using an IDE->FW  
converter.

Firewire is especially well suited to things like movie editting and  
other A/V work, and I'd rather use it than IDE for those kind of  
tasks.  It's not clear that even Ultra320 SCSI is a better choice as  
an interface, although the highest-end SCSI drives are probably more  
reliable.  You'd have to switch up to a fibre-channel SAN to get a  
system which is significantly faster or more fault-tolerant.

[ I don't think so highly of USB2. ]
