That would be an incorrect assumption.
The FireWire controller usually talks to a SATA or PATA interface on
the drive, but it is the FireWire controller that runs the show. The
computer can't see past the FireWire controller.
This demonstrates very well how one goes wrong by just looking at
transfer rates. SATA or PATA are plenty fast, but it is the CPU that
slows the data transfer.
