@todd_a_jacobs Now that I think about it, you're right; Unraid doesn't actually use RAID, and parity is achieved with parity drives rather than striping.Unfortunately, I can't tell you much about ZFS, cache drives, or multiple enclosures as I don't use them. My Unraid server is pretty simple. It uses XFS with 4×4 TB disks (2×data, 2×parity).If you give Unraid and/or TrueNAS a try, I'd love to hear your thoughts on them.
