    After doing a check on the health and performances of my comp,

    the program gives me a red flag for the Avg Disk Queue Lengh with a
    average of 2, minimum of 1 and a max of 6

    I have Western Digital Caviar RE 320 Gb * 3 raid 5 (so good and fast
    disks)

    they are only 1/32 full so lots of room, the disk is defragged, all
    temps files are binned

    As you can see by my comp details I have a good setup, so why do I have
    such bad readings ???

    any help would be helpful

    after reading up, it seems that if I transfert my raid 5 to a raid 1 or
    0 setup it might makes things faster

    Anybody ???????

    That's a very strange question. RAID 0 and RAID 1 are completely
    different and used for very different purposes. To think of them as
    alternatives is certainly very odd.

    RAID 0, in theory, will speed up the computer over no RAID, but in
    practice, it usually does so so little as to be unnoticeable.
    Considering that it also greatly increases the risk to your data, I
    recommend against it.

    I don't know anything about the relative speeds of RAID 1 and RAID 5.

    RAID 1, as I said, is completely different. It's mirroring, used for
    redundancy, not performance.

    Hi

    well it was the raid 5 that was the culpri

    Raid 5 is far more complex than 0 or 1 and fore on-board cards
    changing my set-up back to raid 0 solved the problem straight away,

    I can actually see the difference as just opening HD and windows is fa
    faste

    I think that I shall order a raid car and play around some more,

    Raid 5 I'm sure will work better on a Raid card and I will get bette
    band with thru a card than on the MB, therefore getting even bette
    transfer rates :

    Ken,

    When I do a system health check I get the following information/message
    "Average disk queue length is 3. The disk may be at its maximum transfer
    capacity due to throughput and disk seeks"

    What does this mean and what do iI do about it. I'm not even sure which
    disc it is referring to, I have 2 internal drives and 3 external drives.

    Thanks for your help.

    if I understood all of it correctly it basically means that this is a
    traffic jam while reading writing to the hard disc, that why you see
    sometimes the little blue ring in vista going around as its thinking

    Have you only one HD, or do you have a raid set-up ?, as you didn't
    post your sig so we don't know your set-up
