I discovered that using the noop scheduler helps. However, they seem to have finally fixed this bug.
I'm on Ubuntu 11.10 with 3.3.0-rc5 and these are my results (copying from an external usb drive):
rsync: 733507584 100% 30.89MB/s 0:00:22 (xfer#1, to-check=0/1)
Somebody should verify with 3.2 as I guess this will be the kernel that will ship with Precise.
