I want to build a truenas server with the cheapest CPU I can find that can support ECC RAM: Celeron G4900T + 64gb ECC RAM + 4x18 TB SAS drives.

I don’t have experience with ZFS or with truenas (core or scale), how much important is the CPU?

Use case: hundreds of thousands of small files mostly under 1 mb, but just 2-3 concurrent users

    No, just thousands of small files. Windows takes around a minute to enumerate all the files in the main share via SMB

      You should be good, then. Probably don’t need SSDs for ZIL and L2RC either. Don’t forget to schedule a weekly scrub, to catch bit rot. Essential for large drives.

      That looks more like ARC problem, it can hold a large index of the filesystem if you give it enough room in ram, avoiding the need to seek thousands of files on a spinning disk, which takes time. HDDs are fine for sequential operations, Random IO, which is your usecase, is their biggest weakness.
