Well at least very similar speeds seem not too unreasonable. I am not
sure if the 64bit pointers would hurt the performance of gcc in any way.
It does have to move more bytes around than a 32bit machine. it is
certainly faster at many tasks.

That doesn't say much interesting for sata drives. -t would have been
more interesting.
As far as I know sata drivers always run with dma on, but I may be
wrong.
