Can you characterize the hard drive you're backing up to? Spindle speed, seek latency, write times, etc.
What numbers does a simple copy of a single really large (1+gb) and then a buncha smaller files across this connection yield? Is there another USB port/controller on this machine that you can try out? Any possibility of doing this over a second NIC to a NAS box, with a crossover cable, or over a firewire connection to a different drive?
