    Is it possible to set up 4 hard drives in a raid configuration? If so would it be better to set up 4 100g or 2 200g hard drives?

    Depends on the raid level, with only two drives you would be limited to raid 0(stripe) or raid 1(mirror)

    With four drives you have a lot more options, raid 5(parity), raid 1+0(strip of mirrors), 0+1(mirror of stripes) and more etc....

    Do you require redundancy? speed? or both speed and redundancy?

    If you're planning on going with an onboard raid controller then i'd probably say just go with raid 0 and make sure you backup your data.

    If you're looking at purchasing a decent dedicated raid controller then raid 5 might be an option worth looking into.

    For speed, RAID 0. Just keep in mind if you loose one drive, you loose everything. If you want redundency + speed, you're really better off with a RAID 5. 1+0 is faster, but requires doubling the number of drives.

    RAID 0 2x200 = 400GB - Fastest, no redundency
    RAID 1 2x200 = 200GB - No performance increase, redundency
    RAID 0+1/1+0 = 4x200GB - 400GB Faster, redundency, lots of drives
    RAID 5 = 3x200 = 400GB - Fast, Redundency
    also:
    RAID 5 = 4x200 = 600GB - Fast, Redundency
