    allright what's the point of setting up a raid array with only two hard drives, i thought there were required, and obviously with my knowledge, i have never done this.

    how does a 2 disk raid array work exactly?

    that depends.

    you can either set them up for mirroring, so if one drive goes out, you will still have all your data, or you can stripe them, so that every other bit gets written to an alternating drive, so it makes things faster.

    speed or data redundancy?

    you can only choose one with two drives in your RAID.

    but if you stripe them, you only have half the data
    is there a way to reconstruct the data ?

    That's the disadvantage of striping. If either drive goes out, the whole volume is toast. With mirroring, both drives must fail at the same time for you to lose the volume.

    You would need at least 3 drives if you wanted to have both fault tolerence and performance advantages.
