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
