funny thing is that single most effective way to increase disk I/O 
on windows 7 is to make all transfers non Async  :-)

it has been reported as being as much as 50% faster though all the 
explorer reporting becomes totally wrong... i.e. instead of wasting 
time trying to determine how fast and how much time it takes, it 
just does its copy and reporting is completely off, but its actually 
much faster.

Sounds like a trade-off between throughput and responsiveness
