    I am experiencing extremely shoddy performance with a similar disk/chipset
    combination. I am on an Asus P2B-DS board (440BX) with the following disk
    setup.

    hda: Maxtor 93073U6, ATA DISK drive
    hdc: Maxtor 90840D6, ATA DISK drive
    hdd: Maxtor 90840D6, ATA DISK drive

    I am barely experiencing the same performance you are, after enabling all the
    stuff that's been discussed in this thread. I'd like to determine if this
    disk is dying or if there is something seriously wrong with my kernel. I did
    not seem to experience anything until I went to 2.4.16. hdd seems to be
    headed for the heap, as all tests on it fail. I am stumped; I've read the
    manual and the threads and still haven't extracted proper performance. All
    help is appreciated.

    Thanks,
    AKK

    Following is the information on the other disks and the hdparm test results:
