I’ve seen many people have insane setups to download things automatically and NAS’ with tens of terabytes of capacity, which i don’t understand at all.
I have a 1 tb drive from 2013 of which I’m using ~850GB and most of the space is used by series i have already watched and haven’t bothered to delete.
What are you storing to need so much space and how are you finding so much good content that you actually want to save?
What is easy to find today could be difficult tomorrow. Also original versions could be lost or edited to be more PC and the original stops being sold or streamed.
Disney is removing media from its service for tax breaks. Game servers go offline all of the time making lots of games fully or partially unplayable. Bungie deletes dlc that people have paid for and I’m sure others will be able to chime in with more examples… The point is it better to save it if its important to you.
