I have plugged the drive into Windows XP and transferred a file to it from another computer over my 100Mb LAN and it sits at around 9,000KB's so it is definitely capable of going faster than it currently is on FreeBSD.

So you have an high-speed controller (ehci), but you device is
attaching to the full-speed controller (uhci).
Your transferrate is not surprising with this setup.
Does it make a difference if you connect the device after booting?
You may also want to try another high-speed device or NEC based
controller - VIA ones are known to have problems.
There have been some workarounds for VIA based controller - they might
help you or not.
