Slow RAID 0 RRS feed

  • Question

  • I am running the following:

    Windows 7 Ultimate (build 7600)
    3.20 gigahertz AMD Phenom II X4 955
    512 kilobyte primary memory cache
    2048 kilobyte secondary memory cache
    6144 kilobyte tertiary memory cache
    64-bit ready
    Multi-core (4 total)

    Raid 0: 2x WD Black 1.0TB SATA3 6GB Drives

    BIOSTAR Group TA890FXE

    NVIDIA GeForce GTX 260

     

    I did the preformance tests (without drivers installed and it was appauling as i'd imagine it) and then with the drivers installed.

     

    The final outcome was amazing for everything... but the HDD's. I was shocked. I'm getting a 5.9 score on 2 tb wd black sata 3's? really? thats lower than my 80gb wd sata 2!!

    According to HD TUNE

    Before Driver Updates/Windows Updates:
     16.1 MB/s Min
    242.3 MB/s Max
    167.4 MB/s Avg
     10.3 ms Access Time
    178.6 MB/s Burst Rate
     8.2% CPU Usage

    AFter Driver Update/Windows Udates:

    112.6 MB/s Min
    239.3 MB/s Max
    188.0 MB/s Avg
     10.4 ms Access Time
    166.5 MB/s Burst Rate
     7.4% CPU Usage

    For a RAID 0 (or even a single drive) this is borderline mental handicap.

     

    Someone must be able to suggest something.. this is horrible.

  • This is caused by the driver you installed. It may not work with Windows Experience Index properly. Similar discussion was in the following thread. There are various hardware configurations that have different results.

    "Windows Experience Index" reading for RAID drive is too low

  • I posted there Arthur, Ive disabled write caching, its not just WEI score. look at those speeds from hdtune.. thats ridiculous, ive seen clowns do calculus in their heads faster than i can get my pc to respond.

    I've tried to update the RAID driver in windows but it says its using a more updated version.

     

    Somethings gotta give.

  • You may note that this kind of issues can also be caused by compatibility problems. It does not mean that the performance of the RAID is not good. If you have upgraded everything but it did not help, we can do nothing in the operating system. However you can ignore the index result if you do not experience performance issues.

  • its not just the experience index. i posted drive copy speeds and they are severely low. if i had some generic peice of junk hard drive i might be able to see incompatibility issues.. but these drives are WD brand new TB drives.. i dont see them preforming slower than my old ide 360gb drive as far as copying. the hdd speed is really really slow. there HAS to be something to do check or fix.
