If you’re willing to run at least 4 drives, RAID5 is good too. You get 75% of the space and as long as only one drives dies, you can rebuild the array without data loss. Ideally.

What sort of tests do you run?

What you don’t want to hold onto The Wrecking Crew for your descendants?

If you torrent that means stopping seeding tho

And sneakernets would make personal archives more valuable than ever

My Bravia does some magic that makes video files look better than they do on PC. I’ve started replacing many of my 2160p files with 1080p ones, the difference is often barely noticeable, depending on the quality of the respective rips.

I don’t generally go below 720p but some old stuff that hasn’t been remastered has no reason to go above 480p.

Again, given that OP claims limited expertise, Kodi is a good starting point because of its simplicity.

I’ve mostly stopped using it because I find the Jellyfin apps adequate.

Well, I do use Jellyfin for in-home streaming as my TV has issue with HDR content tinting, and Jellyfin fixes that on-the-fly, but it’s certainly more complex setup than pointing Kodi at a network share

Well, you can just run a reverse proxy container with docker

Wouldn’t Kodi be better suited then? Jellyfin’s strength is its ability to transcode

Nextcloud AIO container runs pretty much without fuss on my VPS, but I don’t use the office features, just file syncing/sharing, contacts and calendar

They didn’t say all at once!

Just resist the urge to download everything at max quality. Some movies don’t need to be 4k, HD is enough.

Yeah but only in non-striping RAID. I had one of those fail after less than one year, RAID5 saved me from data loss.

There’s Feishin that can connect to Jellyfin or Navidrome, on Android I use Symfonium
