If you only need RAID-1 then software RAID is probably best.  It's cheapest 
and provides much better performance than most hardware RAID's.  Also if you

only need 20G of storage then you still may want to consider 120G drives, 
they are much faster than 20G drives.

You can get 40 meg from a software RAID-1 on IDE drives more easily and
