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.

Sand, Dirt & Mud Testing

To test the USB flash drives as if they had been dropped outdoors or at the beach I performed a test where all the flash drives were buried in sand, dirt and mud, separately. After each test the drives were cleaned off with a compressed air dust cleaner and a paper towel. All of the drives passed the transfer tests without any problems

Drop Testing

Testing of the USB flash drives continues with drop testing.

All five flash drives were dropped from a height of 3 feet, 6 feet, 8 feet, and off a roof at ten feet. All drops were onto a hard brick surface. Between each height the drive was tests for functionality.

None of the drops caused any real damage to any of the flash drives aside from some physical cosmetic scratches to the casing. All of the flash drives passed every transfer test after the drop from each height.
