P4C800 RAID Poor Performance

Discussion in 'Asus' started by Len Wassenaar, Jun 23, 2003.

  1. I just installed Win XP Pro on a P4C800D using onboard Promise IDE Raid 0
    using a pair of WD 80G (8meg) hard drives. Raid setup was the automatic
    performance option. Default BIOS settings on mobo.

    Question: Why is the write performance so pathetic at 1/10 of the read
    performance? Running the ATTO tests I get:

    Read: 58 MB/S
    Write: 5 MB/S

    The drives to better writing in IDE ATA mode. Any

    If you search with google you will find a LOT of threads about this question
    ... anyway: if you want to get best raid performance:

    1-install drivers from MSI
    2-Use, if possible, only serial ATA disks
    3-use a mix of PATA+SATA

    and that's just the beginning ..
    Good luck,

    I use two Maxtor DiamondMax Plus9 8MB Ata 133 and one Seagate, Barracuda
    7200.7 80GB 8MB S-ATA and I have exactly the same bad write speed. 5MB/s. I
    use raid 0 .
    I don't want to install all my hundreds of programs again so I really hopes
    there is a work around for this problem.
