Impact/Compressive Testing

 The USB flash drives were tested for resistance against crushing or impact by being run over.
The drives were placed in a line and then run over by a bicycle, a car at idle speed, and then later a car at 30 mph.

These tests yielded the most damage to the flash drives. 3 out of the four flash drive USB connectors were bent when run over by the vehicle at idle speed. Bending them back into shape with a screwdriver allowed them to work. The same damage was done by the car at 30 mph, only greater, beyond repair.
