Now this is what I call a tough USB drive, originally made for the military, this device is completely everything proof, and is made by R and D Electronics under license from the giant lockhead corporation, so there is a lot back ground there.
The USB itself has the following memory available in 32 mb to 4 gb, which will give a variation of applications, the USB is compatible with most operating systems and works in extreme temperatures ranging from -40F to +203F degrees, which would cover a lot places on earth.
As a piece of equipment originally designed for military applications, like field software upgrades, air or ground vehicle data logging, condition monitor systems, embedded training systems, data recorders for unmanned vehicles, and telemetry or flight recorders for rockets and missiles, so it would sufficient for any office conditions, unless there is a nuclear war or something.
Not quite sure of the price or even if buying one would alert the government, but this is some piece of work, and its strange appearance does not really tell you or anyone what it really is, if you see in the street you may think that is was a stopper or something.
