I think your ability to do this is going to depend
on several factors and it's not easy to answer.

This is why sometimes it is easier for a machine
that's not mission-critical to use a cold mirror
instead of a more complex RAID.

I just sync up the mirror disk nightly with rsync
(similar tools like unison are available for Windows).
This means that at the most you lose 1 day's worth
of changes to your data. The mirror disk is really
just a plain disk with regular file systems that
you can mount and use in any machine.

I second this. From my experience, this makes it much easier to handle
the data.

You might even consider a real-cold mirror: take the backup disk
offline, or ensure the server spins it down when it is not used. Many
cheap disks are not able to run 24/7 without breaking down a little too
quickly.

Ensure the disks don't get hot: that reduces lifetime a lot. I tried
putting my server in a small closet, but it became too hot.

For my 4000 tracks, the slimserver uses 26 MB ram.
