hmm.... more specifically, 8-11 Mbps depending on type of USB storage
device. Harddrives work better than flash.

As an example, on my Dell laptop with a T9550@xxxxxxx the command:

   time dd if=/dev/zero of=/tmp/junk oflag=dsync bs=1M count=256

shows the following rates:

Kingston, 8GB stick (enterprise quality versus consumer grade): 9.7 MB/sec

Seagate external drive (older, low end consumer model): 11.6 MB/sec
