My friends run hundreds of TB:s serviced onto the Internet for hobby and pleasure reasons.
It's not all HA, NVMe, web scale stuff, but it's not like a few hundred TB:s is a huge undertaking even for individual nerds with a bit of money to spend or connections at corporations that monotonically decommission hardware and is happy to not have to spend resources getting rid of it.
This summer I bought a used server for 200 euros from an acquaintance, I plan on shoving 140 TB in it and expect some of my future databases to exceed 10 TB in size.
