ahh that's good as I can't reproduce that my machine, but I was
pretty sure, that it's a timing issue.

I'm not really buying into hdparm cached time numbers (-T). -t is
at least usefull to see, that the speed between disk drive and
controller/driver is ok. There could be a regression, but I'd like
to see numbers from more meaningfull benchmarks or even better
real applications.
