I create videos, and back up all of my raw footage. I make weekly videos, and the size ranges from 50GB up to 500GB or more. I have 105TB available, 90TB used at the moment. I also have a fully redundant set of another 105TB. My employer has unfortunately made it very easy to justify hoarding, as they'll sell me reputable used commercial drives for $10/TB.
The video archives are 53TB
TubeArchivist is 19TB
Legally acquired movies and TV is 10TB
Immich is 2TB
Those are the main users of data. A bunch of other folders are using anywhere from a gig to 500GB, but those are basically rounding errors.
