Well I never used RAID so actually I don't know much
about what has to be done exactly.  But basicaly you
just enter some commands which tell Linux to consider
/dev/sda and /dev/sdb as a RAID0 array of disks, and
this result in a third block device
/dev/i_dont_know_how_it_s_called to contains a logical
view of what is in the RAID array (as if it was a single
disk).

I never did something like that before, but I can't see any reason
why this wouldn't work.  So if you just want exact copies, go on,
this looks the simpliest way to do it.
