My school had them everywhere back then. At one point, I owned 2 jaz drives, several Zip drives, and countless disks for each. I later worked the phones during Iomega's click of death scandal. Yeah, I'm old.
I had Zip and Jaz drives as well. A couple years ago a guy at work was doing some weird project where he neede a bunch of zip disks, so I gave him my box of them and he transferred my data to a couple DVDs. Found a lot of photos, old forgotten code of mine, and D&D scenarios I had written and never played. Homebrew spells, magic items, etc... which I'm now using in my campaign. Great treasure trove!
