Converting RAID 0 array to RAID 0+1 - Advice sought.

    I've just built a new machine and have created a stripe set therein
    using a Promise FastTrak 100 TX2 controller and 2 Western Digital
    WD800JB hard Drives.

    Now, I opted to use the PCI IDE controller as I thought It may be
    slightly safer than the onboard one inasmuch as I could always move it
    and the drives 'as is' to another machine if anything went wrong with
    any of the other components.

    Am I right in this assumption or should I have used the onboard
    controller? Will the PCI bus' bandwdth limitations have an adverse
    affect on speeds or is this negligible? My system specs are included
    at the bottom of this post.

    Anyway, i'm digressing a little here as the main pont of this post is
    to determine how I go about converting this 2 drive RAID 0 array into
    a 4 drive RAID 0+1 setup as soon as I get another 2 drives. Can this
    be done non-destructively?
    i.e Will I be able to merely connect each of the two drives as a slave
    on each channel and simply enter the FastBuild utility and rebuild the
    array so that the existing setup is just mirrored onto the two new

    It would save me a lot of trouble if i can do it this way as the
    current stripe set holds my OS etc.
    Anyway, thanks in advance for any advice you may have to offer.
