Writing faster than reading?

edited July 2003 in Hardware
I have conducted a couple of tests in ATTO

My drives are scoring higher in writing than reading, is this normal?

The drives are a WD800JB and aWD1200JB.
I have tested on both the SATA and PATA controller.

The test pictured is performed on the WD1200JB on the SATA controller.

    Those are totally normal attos as far as read/write disparity, but I am concerned because the overall score is very low. 11K is quite a bad score for those drives on a new mobo. Bump the total length up to 32mb first, just to make sure I'm on the right page with you, since I only ever run 32mb length tests. If you bump it to 32mb and your scores still look that bad, we need to fix it.

    Yes run it at 32mb but those scores suck big time even at 4mb.

    At 32 mb you should hit 50,000 or in taht range anyway.

    The pattern I have seen is;
    If the drive is empty, read scores are higher,
    Half full even scores,
    full write scores high.

    But as the others said, that score is worryingly slow. Did you have anything running when you ran the bench?

    I am going to post a new score in a little while.
    I think I have found the flaw.
    I had no SATA driver installed in devicemanager the SATA is labelled as ST3MP28 SCSI controller.

    I think it would help with the right drivers installed.

    I have also tested my other drive a WD800JB it scored four to five times higher.
    I will post a screenshot when I have defragmented the drive.

    Here is a new bench, this time it is the WD800JB on the PATA controller.

    That looks better doesn't it?

    Looks like a new driver improved the score.

    It is the driver from the install cd do not know what version.

    But the scores are improved a lot.

    Yea, that's much better. Though you should be able to squeeze a bit more out of them than that.

    Get yourself some tweaking utilities (like Power Strip) and see if you can crank up that latency.

    Also, check for a newer driver on the web than the one you installed off the CD. If there is newer one available that may give your scores a little polish as well. Oh yeah and defrag it, doing that works wonders.

    Cheers

    Whew.. you scared me for a minute with that 11K score... :)

    LOL primesuspect
    Then it was a good thing that I found my driver disk.
    Now I will mess a bit with the drivers and the latency and see what I can come up with.

    BTW what speed should I expect from these two disks?

    Can you give me some reference results?
