I already have a setup at the house. This 16TB is basically the master cold storage for everything(~12GB of content and personal files) and gives me peace of mind. I can restore the server apps in twenty minutes with its local backups, but... the Jellyfin content, my books, roms, etc, need some parity.

A few months later I might get another and make another copy. I usually buy refurb drives and test them out a bit before running them. I have pretty good luck with them. Most of the time, I'm writing the entire drive on first use so if there's a problem, I'm gonna find it.
