  Three-way mirror?

    I just keep adding 2 more drives as it gets full. Not sure if that’s the best thing.

    I would not trust these kind of dives in the mirror. IMHO RAID6 is the only way.

      Due to risk of failure or risk of data corruption because the mirror can’t tell which drive is right when there’s a difference?

        ZFS or BTRF mirror will know which side is at fault due to checksums. I’m more concern about simultaneous falures of two disks. Rebuilding of a RAID puts lots of pressure on remaining disks, so probability that remaining one dies too is much higher. with RAID6 3 disks need to die to lost date, which is less likely but not impossible.

        The second one.

        Mirroring is good for speed and redundancy, but a storage mechanism with parity checks will all ways be more recoverable. And depending on the array you have far more storage available.

      Or SnapRaid
