Thanks everyone for the quick replies.
I mounted with mount -o sync /dev/sdb1
and now a 2 minute transfer takes 8 minutes.
Does anyone have a script for monitoring with iostat or vmstat while in
async mode?
I'm thinking a bash equivalent to the disk monitor on gkrellm which
allows me to know when a transfer has completed.
Cheers.

Slightly-slower-hack: add the 'sync' option to whatever script or config
file is used to mount the device (/etc/fstab, udev rules, KDE service
menu etc). That way all writes will be synchronised automatically. For example if I transfer 200mb to a usb disk the
copy command takes
about 30 seconds before it returns and the data takes about 5 minutes
before it is actually finished being transferred and the device is
unmountable.

(cp -a /xxx /usb_device && sync) &
But remember sync flushes _everything_.
