You will get dozens of divergent opinions on this.  :-)

Any RAID 1 is better than none; I'm in the "hardware's better" camp,
and everyone's reasons, on both sides, are in last months archives, so
I won't rehash mine here, and hopefully everyone will follow suit.

On the other hand: you're better off having root and (especially) boot
on a separate drive, and yes, mirroring them occasionally to dedicated
partitions on one (or more) of your other drives -- you don't want this
to be automatic since saving your ass from administrative screwups is
one of it's major jobs.

Do that with a pre-configured script calling dd, backing up to
partitions that stay unmounted.

But having your OS and your media on separate spindles will definitely
be a win.
