Does UGreen support ECC memory? As far as I've read online, it's crucial for Truenas.

  In part that’s an interesting question. Some of the processors on the Ugreen line are Xeons, so they should support ECC, but I’m not sure the MB does. But you don’t really need ECC for ZFS. That’s a kind of myth that has been debunked several times. Sure, it’s always good, but ZFS works just fine without it. (I’m on my phone so it’s dificult to find a good source for the claim, but if you search a bit, you’ll find some good blog posts talking about it).

    Well, that's the thing. I've also found some posts saying it's a myth and you'd be fine, but the ratio of posts recommending ECC to posts debunking the myth is like 10:1.

      The important key point is that you will not lose anything by using ZFS without ECC compared to using any other file system without ECC. The myth is that you specifically need ECC if you’ll be using ZFS, not that ECC is a really good idea for any file system. https://jrs-s.net/2015/02/03/will-zfs-and-non-ecc-ram-kill-your-data/ https://jrs-s.net/2015/02/03/will-zfs-and-non-ecc-ram-kill-y...
