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 have a tiny Kingston microduo 3c drive on my keychain with some tech toolkit stuff. It is small and robust. Think I have had it knocking around for the last 4 years.
