??? Microsoft RAID/Disk Manager -vs- Intel Matrix Storage Mgr/ROM

    My question.. I created a RAID 0 Volume using Intel's ROM Utility (NOT
    Microsoft RAID). Should I ignore Microsoft's Disk Manager as it relates to
    that RAID Volume.

    These points seemed odd that Microsoft's Disk Manager...
    1. reports my RAID 0 Volume as Basic (not Dynamic)
    2. displays the entire Disk 0 as "Primary Partition" instead of a "Striped
    3. does not display the member drives in the Array.. instead it displays
    the entire Raid 0 Array as Disk 0.

    I started with 2 blank 500GB WD HDD's.. using the ROM Utility (Intel Matrix
    Storage Utility - ICH8R) to create a Raid 0 array as a single partition.
    Next, I installed a clean copy of Vista Home Premium on that single large
    Then I installed the Intel Matrix Storage Manager which correctly displayed
    the RAID 0 Array, the Volume, and the 2 member WD HDD's.

    (dumb question - Does Microsoft Vista function with all the performance
    benefits of RAID 0 even though Disk Manager can NOT display the actual

    Thanks in advance for your help!

    Hi Ross,

    This is perfectly normal behaviour. As far as Vista is concerned, a RAID
    array created in hardware appears as a single disk in Disk Manager. The
    reason why the Intel Matrix Storage Manager is able to display the correct
    details is because it is able to access them from the RAID controller itself.
    To Vista, the RAID controller appears as a SCSI device. If, however, you had
    chosen to create a software array in Vista, then the Disk Manager would
    probably display it correctly. Although I have RAID, I too have hardware RAID
    and have not tried the software version - perhaps someone who has can shed
    some light on this issue. Hardware RAID which is built-in to the motherboard
    is, in my opinion, the best option for those who wish to use RAID. A hardware
    RAID solution is always going to be better than a software solution and much
    more reliable. To answer your dumb question - as long as Disk Manager sees
    the total of the array (in your case slightly less than 1TB) then it should
    be functioning correctly.
