    That's what i was thinking, but 30MB/s seems to be quite an exaggeration.
    On my
    Intel Corporation 82371AB PIIX4 IDE (rev 01), ide chipset my master (10.2GB
    maxtor 7200rpm UDMA66) drive i get ~15-16MB/s and on my slave (same
    interface, 20.1GB maxtor 7200rpm UDMA66), i get ~13MB/s. This goes against
    logic as the bigger the drive the faster the transferrate should be, and
    it's about half of your estimate of Michael's 40GB. Is this due to the
    slow disk access of 2.4.0-test10-preX ? Or am i experiencing a bug here?
    Both drives are operating at UDMA33 mode (according to hdparm) and both
    drives are set to using 32bit, dma, 16 sector read ahead and 16 sector
    multi-access mode. I've posted results i've gotten from bonnie and
    bonnie++ before, in all cases, the performance seems to be lacking for the
    kind of hardware i have.
