If you have music on your server, I’d strongly recommend checking it out. I believe it was started as a side project by the Plex devs and it’s a way better music player than the one built into the Plex apps.

You’re 100% correct. I always find it funny how hardcore some people are with jellyfin vs Plex. I’ll probably end up getting downvotes on this but imo Plex is way simpler to setup and keep running, and as a lifetime pass owner, I’ve very rarely felt like my experience has been deteriorated by any of the changes that the jellyfin crowd freaks out about. Plus plexamp is honestly such a great music player. I’ll happily keep running Plex for the foreseeable future.

Other than ZFS as someone mentioned already, they also offer dual drive parity now. IMO it’s a good balance to also allow a very flexible and easily expandable array.
