Setting elevator=noop solve the problem for me, the write speed to usb stick is stable, about 5-6 mb/sec all the time. But now sometimes I see the HDD performance problems while system write to usb.
Maybe try other elevator types?
Completely Fair Queuing — elevator=cfq
Deadline — elevator=deadline
NOOP — elevator=noop
Anticipatory — elevator=as
