Without going into video media, I've got around 2-3TB of photos (in RAW format) and my ripped/downloaded music collection is about the same size. Probably got about 5TB of device backups and a similar amount of retro games ROMs/disk images

I think between my desktop PC and server I've got about 70-80TB of storage (though not all of it is usable for redundancy)

I could see myself building a new NAS in a couple of years that would make use of a few of those drives if the economics work out
