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.
