That seems like awful disk performance. But, why would that have
anything to do per-se with is being a mini-ITX motherboard? If its
PCI and IDE chipsets are ok, and Linux recognizes them correctly, then
the disk should work just as well as on a larger motherboard, right?
Did you use the hdparm -i -I -tT options to check that Linux isn't
putting the disk controller into the wrong mode?
