This is going to be a big question, with a lot of "it depends", but here goes anyway.
I would call myself the average Unraid user: Arrs, Plex, Nextcloud, and other small "standard" dockers running. Nothing all to wild.
I have 6 HDD's for storage, 1 parity, 1 2.5" SSD for cache. I'm happy with it - it works, but I do wonder if I'm getting everything out of my equipment, or following "best practices".
I read a lot of people have ZFS cache pools, ZFS this, ZFS that. But I do wonder: am I doing anything wrong? In the sense that, I should use my one m.2 nvme slot for my cache for best performance. It won't be mirroed, but instead I can have it backed-up somewhere else. Or is it worth the investment and buy a PCI-e card to hold several nvme's for a raid setup? And, since I have the space in my chassi - run at least two HDD for parity. Should I have scheduled backup of my cache/appdata?
It's just me that uses my server, with the occasional "visit" from my brother who buffers content on his end to watch at his home.
I watch spaceinvader one videos, and there are some setups that seem interesting - but then I think, "do I really need that?"
This is most probably just a big brain fart, but I hope you guys understand what I'm asking.
