I set up Jellyfin on my main machine as a test. I enjoy the experience and want to migrate to a NAS, for better reachability in my network. I am a beginner when it comes to networks.

I currently use a single 20TB HDD (current usage 80%) and another 4TB HDD is around somewhere. I was wondering what my options and recommended solutions are. Should I get 1, 2, or more 20TB drives? I want some redundancy, but don't want to invest into too many drives.

Looking forward to any tips or resources to read up on. Thanks.

With 20 TB drives, I would have concerns about a drive failure during a rebuild. I suggest at least 3 drives and a config that can handle 2 failures.

Unless everything is replaceable.

Spot on.

Plan a little for growth, maybe a 5 drive unit with 12TB drives, with duplicate parity.

Optionally: Two 20 TB drives mirrored, cloud backup (e.g. Storj. io or another), perhaps another local 20TB drive that's a backup or a local replica.

Edit: any approach needs to include off-site backup, and that backup needs to be tested, at least quarterly.
