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

Single-device storage capacities have been growing faster than their throughput, which makes for long days.  (I just migrated ~340 GB to a new/old PIII 600 MHz machine with LUKS encryption at ~10 MB/s; 10 hours over the wire, plus more time ironing out wrinkles.)
