    BTRFS can work across multiple disks much like ZFS. It supports RAID 0/1/10 but I can’t tell you about performance relative to ZFS.

    Just be sure you do NOT use BTRFS’s RAID5/6. It’s notoriously buggy and even the official docs warn that it is only for testing/development purposes. See https://btrfs.readthedocs.io/en/latest/btrfs-man5.html#raid56-status-and-recommended-practices

    Edit: Another interesting thing to note between the two file systems is deduplication. ZFS supports automatic deduplication (although it requires a lot of memory). BTRFS supports deduplication but does not have built-in automatic dedup. You can use external tools to perform either file-level or block-level deduplication on BTRFS volumes: https://btrfs.readthedocs.io/en/latest/Deduplication.html

      Thanks for the insight!

      I may have to resort to using BTRFS for this host eventually if ZFS fails me. I do not expect a lot of duplication on a host, even if I have it, who cares I have 60 TB despite the raid 10 architecture. Having something with kernel support may be a better approach anyways.

      It’s interesting to me that it struggles with raid 5 and 6 though. I would have expected that to be easy to provide.
