I've seen a lot of articles and blog posts like this, but their numbers never seem to make sense. It says that reading through a 4-disk 8 TB array you only have a 15% chance of success. I have full-array BTRFS scrubbing scheduled monthly, according to this my array should have reported errors many times a year...

And of course, no matter what, no form of RAID/ZFS is a backup.
