Total combined storage if I don't count offline backup drives is a bit more than 25TB, though I got another 8TB SSD today so that'll be going up soon.
I would say about half of that storage is filled with a number of different archives, lots of video, music, and game stuff just lying around. I also do not like to delete anything ever if I can avoid it. Basically just a hoarder, but I prefer to call it archival lol. I actually do maintain a ~1.4TB or so archive of content for 20 years of stuff from a rhythm game called Stepmania.
Just voted! Looks like water and coffee are going strong so far, which I also ended up voting for on top too. Lots of super sugary stuff, honestly having an herbal tea, coffee, or sparkling water I feel much better after vs a soda or juice.
