Ha ha -- regarding the drive comments, it looks like my humour detector was working just fine ;-)
And regarding mirror vdevs etc, I can see the usefulness of being able to build a mirror vdev of multiple drives for cases where you have really critical data -- e.g. a single 4-drive mirror vdev. I suppose regular backups can help with critical data too. I use a 2-drive mirror vdev for ZFS boot, but prefer RAID-Z2 for the main data pool, although I may consider RAID-Z3 in future. For 2-drive mirror vdevs, 2 drives die and data=toast. A RAID-Z2 vdev would still be readable, although whether you'd have enough time/luck to survive the required two resilvers is debateable. With mirrors though, I suppose resilver time would be quicker. I expect you would have some insightful comments in this area.
