David,
I'm cleaning out my Inbox, and I couldn't remember if I saved this

Anyway, since I probably didn't, here are a couple links to clearer
info than I can give:
Quick&Dirty overview:

RAID management is more of an art than a skill-set. The number and
range of variables is staggering. And I'm a rank amateur....

A multi-channel adapter or multiple adapters, running JBOD, with
intelligent filesystem groupings, will probably boost your speed as much
as RAID will. (Assuming a single-user general-use Unix desktop.) RAID
can be tuned to big sequential reads or writes, or a lot of small r/w,
but it's damn difficult to get middle-ground or all-around performance.

All that said, it's good practice and fun.

Doc - As someone who never played with RAID before, can you provide an
example setup, or two?
