I saw a really cool concept secure usb drive that used a physical lock. It looked like this drive, except the usb connector was on the other end, and extended out to about 1mm from the lock’s u-bar. You couldn’t use the drive when it was locked because it would be impossible to insert the drive into any usb port. It’s not good enough for high-importance documents like government stuff because it’s not technically possible to access the port with some custom plugs.”]
