Does anyone have strong opinions about #Unraid vs. #TrueNAS? I'm a bit unhappy with most of the software-based #RAID systems I've tried, and a lot of the hardware-based RAID systems either don't support different sized drive pools, don't support drives above or below a certain size, limit you to only certain RAID levels, or don't allow you to grow the array without a full rebuild.
There are no silver bullets. Still, what offers the best set of options, and do either work as a #Thunderbolt #DAS?

@todd_a_jacobs I haven't used TrueNAS, but I've been very happy with Unraid as a consumer. It pretty much "just works" and is perfect for me as a storage server at home.
I have no idea if it works as a Thunsevolt DAS though.

@dHeinemann 517 pages of documentation were a bit daunting; it seems to defaults to XFS or BTRFS, neither supporting RAID 5 or 6. But it looks like it supports double parity with ZFS in at least two ways, so it seems potentially useable for me. The biggest limit seems to be stuffing two parity drives & two cache SSDs into an enclosure with older (and smaller) data drives. If it works across multiple enclosures then it looks like a good choice despite being closed source.

@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.
