With raid0 you will benefit speedwise, but will lose what comes
to reliability. The fault on one drive will propably rend 
your whole raid0 array useless.

You are in correct base :)

First take a look at, or preferrably read it through with thought
http://www.linuxdoc.org/HOWTO/Software-RAID-HOWTO.html

Then you might want to get linux 2.2.14 
and patch it with: 
http://people.redhat.com/mingo/raid-patches/raid-2.2.14-B1

Also get and compile this for userland tools:
http://people.redhat.com/mingo/raid-patches/raidtools-dangerous-0.90-20000116.tar.gz

and you should be ready to go.
