Hmm, in my case the maximum value i can use is 128, and i cannot see a
difference between 128 and 16 either. It didn't do harm. My guess that
this might impact throughput was based on the assumption that the
overhead increases with smaller sizes. I might be wrong.
Do you have a max_hw_sectors_kb greater than 128? I think it has changed
somewhere during the last kernel versions. I seem to remember that this
was 256 once..
