echo 10 > dirty_writeback_centisecs
echo 10 > dirty_expire_centisecs

Now it should basically write to the stick continously instead of every 3000 centisecs (30 secs).

I learned when I found that transferring terabytes through my gigabit results in 30s long pauses, then 80mb/s for a few seconds and then another pause.

The same principle should be applicable to usb sticks, although it won't explain why usb harddrives are much faster...
