I sometimes feel that I have the online equivalent of people who just shop to have stuff. I have an archive of articles I need to read - print to PDF just to be sure - if I had not deleted hundreds of hours, I would have podcasts to fill this year and the next.
I download Linux ISOs and feel I should keep them because someone may drop by who would need the latest Opensuse, Fedora, Slackware, Arch, Frugalware et cetera.
I find Youtube videos - documentaries, shows and movies I want to watch. I download them just to be sure.
If I focused entirely on all the stuff I have pulled down and have stored, I would be occupied for a month.
I was considering getting a new hard drive - my latest Thinkpad came with the 60 gig drive that was the default when it was new. It may just be a good idea that I do not.
