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.
