I’m looking for a USB3 flash drive for my wallet, which means it has to be exceedingly thin. Ideally, I’d want something like a Super Talent Pico-C (pictured) or Verbatim Tuff n Tiny, with exposed contacts, as this design allows for much thinner overall product dimensions. However, all the USB3 drives I’ve found have the rectangular housings around the contacts, perhaps because USB3 specs require it. Has anyone had better luck? Thanks!

EDIT: PQI U821V is 4mm/0.16″ thick, but it’s got those enclosed contacts. Getting rid of that case could halve the thickness!
