Thank you to Paul and Scott for their input on this. I did a bit more
digging and found this link:

As Paul has noted, Firewire seems to be the faster interface for external
hard drives. It is almost as fast as a direct SATA interface, but is more
convenient (in my view). Hope this information may help others make and
informed decision.

While I've not yet tried utilizing the USB 2.0 interface to capture video, 
experienced friends of mine have told me that, while the USB spec is faster,

it does not maintain that speed in a steady-state fashion. The difference is

much like SCSI vs. IDE. There are some fast IDE drives out there, but their 
steady-state transfer, read, and write speeds are nowhere close to what a 
similar speed rated SCSI drive can maintain. If you plan to do video 
capture, in my opinion, the Firewire interface is the way to go.
