SSD is just shockproof. Indeed, how much acceleration do you have to
subject it to have lightweight circuit board with ICs (Intergated
Circuits) to subject for something to crack? On the other hand,
everyone have seen interior mechanical design of hard drive. to brake
it will take much less acceleration.
