I feel like it’s not something you see very often here compared to other items like knives and fidget items.
I have a JEYI 2230 NVMe case with a 1TB drive I keep on my keychain for backups of things that would be annoying to lose like my AntennaPod stats
I keep a USBC thumb drive in the trunk of the car. It contains my password database and 2fa codes. These files are to get into my Proton Drive where I have anything important backed up.
