You should try really confusing it & it really slows down. I was
backing up to a firewire external hdd from both a USB2 external hdd &
the internal ide hdd & to put it mildly I was not getting a good
throughput.

Dunno why. Played a little & stopping either input (from IDE or USB2 )
massively increased the throughput to the fw ext hdd.

So it ended up as sequential copy/backup which annoyed as I was keen on
lunch at the time.
