The chart also doesn’t specify what hardware the calculation is based on. If it’s “1 year to crack for your average desktop PC”, then a server farm will do so in minutes.

Right, totally forgot about that step.

Haven’t used it myself, but similar to casa os there is also cosmos os, which looking here seems to offer some build in storage management options. Maybe this could be worth looking into?

openmediavault is ok for raid, but the containers aren’t one click wonder like in other NAS OSes

Since OMV also uses docker compose with a build in GUI to manage them, I don’t assume this would be what OP is looking for either? Unless trueNAS also comes with some repository of preconfigured compose files.

I am currently using Openmediavault for my NAS and can confirm that with an official plugin so far I havent had any issue with my ZFS pool (that I migrated from trueNAS scale since I didn’t like their kubernetes use and truecharts, but as someone mentions they seem to switch to docker).

Otherwise I am happy as well, but I am far from a poweruser.
