Why? Ok, I can see if you needed something available 24/7 RAID1
(presumably) might give you that but what if the system hardware fails?

I use HP microservers a lot. The main NAS is one of those. If the
hardware fails, I swap it for a spare. If a disk fails (happened once in
9 years) then it's RAID-1 so it's easy to replace the faulty disk (cold
swap, but very fast) and rebuild the array.

Also, what are you doing for the backups of the NAS itself?

Three overlapping backup strategies, two of which are off-site.

BTW, they are all Western Digital Red now. The one that failed wasn't -
it was a Seagate.

I did have one other WD failure - at 37 hours, while I was setting up a
new system. Replaced very quickly by WD.
