"very nice" with a 4110 Passmark CPU? Seriously, I mean you get 6000+ in some passively cooled tablets from 5+ years ago. That will do only to use it with the most basic RAID, probably with something like ext4 on top of it and to use it as an appliance. If you want ZFS and to run something else too not just to serve some files you'd better build a half-decent reasonable machine.

RAID is for uptime or speed, not for this. It also comes with the dubious feature that you can
lose
your
data
once more
without any disk failures

This question has been asked many times. Have multiple copies, replace bad copies with copies. That's it.

Remind me just about when the last supported Windows 10 version goes out of support. If you look outside our echo chamber already spinning rust is niche technology.

That's the ideal use case for snapraid.

Nextcloud, syncthing, immich. These are just a few, I'm sure there are more.

These remind me of the discussions around year 2000 on photo.net about how digital pictures are useless and how bad is digital compared with film:

• you can see the pictures directly on the film
• you can buy film at the corner store and have "infinite memory", it's much cheaper too (they didn't count that you'd reuse the flash and take more pictures than you could ever afford all your life on film!)
• you can print the film and make paper pictures in 1h mostly everywhere
• you could share these with your parents or send them via snail mail and so on
• prints and film last for centuries or so and people have this or that old picture but lost their Word document they were working on last week

We know how that ended, and film cameras ended being mainstream WELL before phone cameras started to be any good.

In a move that mirrors the current situation with flash only two categories were left with film:

• power users that weren't satisfied with the resolution that you could get from digital cameras at first (as now we have DHers who can't go to SSDs because of the size they need)
• "lost in time" users that didn't know things moved on and picked up their film camera for vacation, like we have every now and then someone asking about 500GB or 1TB spinning rust

The answer is ALWAYS 42!
