70-85 MB/s (?) using Firewire II (800 Mbps)? I am able to get ~40 MB/s on
Firewire I (400 Mbps).

cp -r
I assume that you need copy all the data. If you can avoid copying,
rsync can, of course be (much?) faster, depending on the saving.
However the mere work it ddoes for scanning

Or is 30MBps about as good as I can get from the combination of the USB
software and hardware?
USB is pretty lousy for speed, partly because it is hub-based and has
overhead.
USB 3 will be very fast, though.

30 MB/s is good for USB. You need Firewire, eSATA, or an internal drive
to go faster.
