The real question is:
How do people have so much media to fill up those drives?
Followed by: how do people have so much time to watch that media?
Followed by: human driven climate change is real. How can people waste energy just to hoard media that they rarely ever see again?
I understand somehow if you are torrenting and contributing to the sharing ecosystem, but just hoarding?
No, I'm trying to understand why someone would store so many pictures. 20TB is enough for 330 4K movies or 10,000 1080P movies.
"Just in case I need it" is the principle of hoarding.
