Final Scores

Remember that these aren't highly scientific experiments and my grading system is arbitrary - my goal is to get a sense of which devices are the most robust relative to the rest of the market. If I'm unable to cause any data loss then a device should get an "A" rating, while a device that is quite easy to destroy gets an "F" - anything in between is a grey area.

 Three Tests were performed.
