    I suggest a little reading.
    http://en.wikipedia.org/wiki/RAID

    There are multiple raid options, depending on what you want to do... Most of the info you need to know is in the wiki page though.

    Most you can do with a 30GB and a 160GB is JBOD (Just a Bunch Of Disks), which doesn't do you any good.

    For RAID0 (striping - performance), you need two (or more) disks of the same size, so that is a no-go

    For RAID1 (mirroring - safety), you don't technically need same size disks, but the mirror will be as large as the smallest disk; the rest you will not be able to use, so that pretty much takes care of that option too

    All other RAID levels require more than 2 disks, so they are no option for you anyway.

    HTH

    PS: Why would you want to do RAID? I would tend to think that if you don't know what it is and the different options, you probably don't need it.
