I think dd is the right tool for the job. Consider using pv though. It can be much much faster.

Take a look at tubearchivisit. Works great and is in development.

Sonarr prowlarr radarr and many more. These are very powerful media download managers. I recommend using usenet.

One router (opnsense) a big Poe switch and unifi aps made a huge difference. Also wiring Ethernet everywhere helped a lot.

Previously we had devolo mesh plugs.

Ahh nice good to know. For my use case I’d rather not distribute the certificates to all my services.

True multiple drives speed up reads significantly. As long as the videos are sequential read speeds can be very fast (600MB/s) even on one drive though. Results may vary.

I have a ~40TB HDD array and jellyfin is super fast. Just put the database and cache files on a SSD.

For bulk storage of 4k videos with high bitrates HDDs are way cheaper.

Full pass through has no advantage when my reverse proxy terminates ssl and internal services are http only right?

Regardless of fqdn nginx has to decrypt and restream anyways.

I think mixing RAM sticks is mostly fine today. Maybe you won’t get 100% performance but I don’t think it will be very noticeable. You may still run into issues with some capacity combinations depending on the mainboard/cpu. Regarding clock speeds usually all run on the clock of the slowest one.

Matching RAM latency also matters for performance.

When using different capacity RAM channels matter so take care on the order of population.
