How to choose a home NAS system?

Question

ZFS

I wondered about installing home storage. There is a j3455m, 8GB RAM, 2TB HDD available.
But storage can be called a stretch, more will be used for torrents, content distribution on 4k TV via PLEX, and virtualization of a couple of systems with almost no load.
I installed FreeNas the other day, and I was surprised, 5GB of RAM consumption, in the absence of reading / writing, disabled deduplication and compression, where have you seen it!
Advise pzhl which system to choose for installation, so that it eats a maximum of 3-4 GB of RAM, and preferably less.
It is desirable that it be possible to use not ZFS as a file system, but the same EXT4, which suits me perfectly. Or perhaps you know where to tweak, cut down, so that the RAM does not bite off tons, maybe a cache or something else
I would appreciate any help and ideas

Answer 1

Try OpenMediaVault

Answer 2

will be used for torrents, distribution of content to 4k TV via PLEX, and virtualization of a couple of systems with almost
load other applications (not for the sake of performance) - ZFS gives it away.
Seen many times on Linux.

If you don't need a GUI, use Debian. If you want a GUI - try OMV (from which, however, many plugins were picked up).
