Upgrading to a QNAP NAS Jellyfin server

[larsgregersen]

I have been using a Raspberry Pi 4 as my Jellyfin server. It has worked nicely, but seems to be as the end of support for Jellyfin 10.10.

So I'm thinking about getting a QNAP TS-264 NAS to be used as Jellyfin server.

Does it work as a Jellyfin server? 

Is it powerful enough to serve 4K videos with subtitles?
