    Question A question about RAID.

    When my 36gig Raptor failed a while back under warranty, they sent me back a 70 gig drive which I thought was pretty cool, except I had the drives in a RAID0. I shouldíve made the other drive fail while it was still under warranty but I didnít.

    If I make a raid with the two drives, can Windows still see the reminder of the larger drive?

    Or *poof* that extra space is gone? I know itís best to make a raid0 with two of the same drives with the same firmware but this is what I have to work with.

    I was thinking of putting my OS on a 20gig ATA133 Maxtor drive and my games on the raid. With the extra space for random storage if Windows will see it.

    Correct..when mixing drives in RAID, the RAID will only match sizes for the smallest, and slowest.

    So a 36 gig, and a 72 gig...RAID will only work with 36 gigs of each drive...the remaining half of the 72 gig drive will go wasted.

    Thatís what I was getting at, I knew it would make a raid equivalent of the smallest drive. I was just wondering if the rest of the larger drive would be unusable or useable by Windows.

    If you're doing software RAID...it can.
    With most hardware controllers...no.
    With a few oddball controllers and some setups with JBOD..yes.

    To be honest, itís not worth the trouble of trying unless I know itís for certain. I have an onboard Silicon Image RAID chip 3114.

    Raiding two different kinds of drives isn't recommended. I've tried it in the past and I've found that software RAID works ok in terms of buillding larger partitions (if that's what ur going for) but ur probably trying to go for speed, in which case I'd have to say that you'd be better off doing hardware RAID. This is either setup through the BIOS (if motherboard supports it) or through the expansion card's firmware settings (u'll be prompted sometime at start up to enter the setup for the card).

    BTW is the raid array the main drive for your windows / os partition?
