My 36TB NAS is almost full and almost everything I've seen. Stuff I'll definitely not going to watch again I throw away, stuff I don't like I throw away. I download everything automatically with Radarr and Sonarr using usenet. Hoarding data you never use is just, a waste of space. Upgrading storage space isn't fun anymore with the prices of drives all fucked up due to AI. I can find anything I want, I only preserve really old stuff as it might get harder to find over time.
I was saving up for an extra NAS with drives adding up to ~100TB, to make a less protected media stream for friends. It first was 2200 euros. When I had the money I checked, 3 months later, it was suddenly 4400 euros. 2 weeks later 6800. I don't even want to know how much it is right now. So we're back to when I was young, when you had to be responsible and selective with managing stored data. Sigh.
