Apparently my speeds are pretty decent, 
as this this advertised speed relates to 
read speed, and write one is pretty weak.

People are reporting

62-70MB/s read and 
17-31MB/s write. 

Are you saying that disk clearly bumping
from 40MB/s read barrier (as I saw in midnight 
commander is my imagination or it's cause is totally 
unrelated to OS?

I thought it's worth investigating, as FreeBSD
coincidentally reports USB 2.0 ports as such.
