Julian, you lost me. Mirroring is Raid 1 and only HAS two disks. We're not
talking Raid 5 where an odd number of disks would come into play.
Heck, XP Pro will mirror without hardware.
Now that is not what I advocate. I use a decent increment backup strategy
(Dantz Retrospect) to an external drive and rotate external drives offsite.
