Hmm, that seems more like the kind of speed I would expect. Did you mount with the "sync" option? If not, did you sync to be sure it's not just being cached in the background? Or copy enough data to exhaust the disk cache buffers on your PC.

Here's my info from lsusb -v, everything seems normal to me.

Code:
