Your only choice would be a mirror, as you only have two bays. RAIDZ2 needs at least 4 drives to be useful.

Have you checked that you can actually run a different OS on the UGREEN NAS?

Considering the services you want to run on the machine you’ll want all the RAM you can get.

Also, the CPU is already weak by today’s standard, especially with “heavier” workloads like Immich machine learning.

I’ve got a 4-bay ugreen nas with truenas on it, works great. (The non plus model)

  That’s great! What software do you use it for? How does it perform?

    I’ve got the arr stack, nextcloud and immich, with 16gb ram and I’m pretty sure I shouldn’t add anything else.

    That’s actually fire, do you mean that you shouldn’t add anything more services (ram is full) or that you shouldn’t add any more ram? Anyways sounds good, I won’t be using the arr stack probably so adding a few more services won’t hurt I guess…. Is performance great? Is it responsive?

Sorry, I meant RAIDZ1 (which is the same as mirror I think?) I’ll edit the post. Anyways, Yes, I did my research and I can run TrueNAS; I plan to buy a 128gb m2 ssd for the boot device.

Ok, so I need plenty of RAM. Do you have an idea of what the impact of something like 16 vs 32 gb of ram would be? Sluggish performance on apps would be a problem for me, but I can accept if tasks take longer.

Got it about the CPU. I have been wondering about that too. But I heard people running immich on worse CPUs and they say the only problem is that initial ML tasks take longer (couple of days tipically), but once they’re done you’re good.

Do you have another build to suggest in the same/slightly higher price range that you think would better specs for me?

  Nothing besides a mirror makes sense with only 2 storage bays. The overhead would only increase for absolutely no gain.

    Got it. I’ll go with mirror than. Thx

  RaidZ1 is not the same as a mirror. I'm not sure if you are allowed to have Z1 with only 2 disks, but if you are you still shouldn't because while it scales down that far it still does parity calculations and writes that to the second disk instead of just writing a copy of the data (the parity calculations probably result in the same data, but I doubt this is optimized)

    Yeah, you’re right, I thought RAIDZ1 was ZFS’ RAID1 implementation (🤦‍♂️), while it’s actually called mirror. I’ll just do a mirror.
