Using USB2.0 hard drives (performance) on FreeBSD 5.3

I need extra disk space on one of my machines (in short order). So I
decided to experiment with attaching a USB2.0 hard drive (Maxtor
OneTouch) to the system (SIIG PCI controller). I use a OneTouch on my
Windows/XP sytem and it works really well.
I wanted to explore placing my mailstore on an external USB2.0 drive -
would be easy to port the data to another system if I needed.
However, in experimenting with replicating some data (via rsync), I'm
wondering if this is a bad idea. While rsyncing data over the wire to
the USB2.0 drive (mirroring some data, basically), the shell response to
something like "ls" would hang (eventually completed, but much later).
I wonder if someone can advise about the use of this drive for that
purpose (mailstore) and if there may be some tunables I would need to
tweak to get better performance.
