Extremely slow HDD write performance with GigaRAID on KNXP

    I finally got rid of my Soyo Dragon+ Via KT266A board and I had high
    hopes I can get rid of all the problems it made but it seems my
    problems just got worse with the KNXP :(

    Here is the biggest problem I have at the moment and my setup:

    * KNXP with P4 2.4C and 1 GB RAM (2x 512 PC400)
    * Silicon Image controller is disabled and nothing attached to it.
    * Intel SATA ports have 2 Maxtor 120 GB SATA drives in RAID0 (WinXP is
    booting from these, read & write performance is as expected on this
    * Intel PATA ports have 4 optical drives attached (all seem to work
    * GigaRAID has a Maxtor 160 GB PATA drive (diamondmax9 with 8mb cache)
    attached on the primary port as master. read performance is OK (as
    good as it was on the Via board on a Via port previously) but write
    performance is *extremely* slow, according to hdtach 2.7 MB/s average
    write transfer rate (and I don't think it's wrong it IS that slow).

    The GigaRAID has been configured to ATA (takes an eternity to detect
    the drive on bootup) and now as RAID with the HD in "normal" mode.
    both time it's the same, read performance is OK, write performance is
    at 3 MB/s...

    Is there any way to resolve this?

    BIOS version is F6 btw.
