If I had only one drive on my PC, probably a laptop, I'd put in that 8TB SSD, probably the Sabrent dive, although I know ridiculously expensive. I hate thinking about space and managing the data (not organizing, which I enjoy but just taking things off and on). I don't feel like I download that much random stuff though.
I don't think I'm a data hoarder, at least like the folks I've seen on Reddit. I have a bunch of hardware but right now run 3 computers. Storage wise on my NAS, I'm at 50TB and it doesn't feel like that much to me. I have data duplication on though. I don't even really have any umm linux iso's... it's so far mostly some of my steam library, my video editing projects and personal photos/videos. Later I want to get into even more content creation (make more 4K videos, make games, run some kind of AI LLM, etc).
