I have about 24TB, lots of stuff backed up over many years, and not all of it pirated. In making backups over such a long period of time, I’ve actually managed to make redundant backups, so a recent project of mine is to just go to my NAS and organize, consolidate, and otherwise delete things I don’t actually wish to keep. I’ve saved a couple TBs and I hope to free up a few more TBs.
