I love saving and never deleting things.
Current 2TB drive has my budding tokusatsu collection and assortment of movies I've torrented over the years.
Isos and their emus take up a heft portion as well.
And porn. Ive been saving porn since like 2012 with the fear some of my favorite videos to jork it too would vanish. Now that some states require an Id to watch porn, I laugh at anyone who ever didn't save an mp4 of their favorite titties.
