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?
That really depends on how you treat the media you download. Is it just a temp buffer that you delete after watching or is it a collection you grow and curate over time.
