Why Your Solid State Drive Failure Is Going to Be Horrible

Your computer’s inevitable solid state drive failure is going to give you a very bad day. Maybe. To create amazingly fast solid state drives, engineers had to exploit quantum mechanics. But, it comes with a cost. Quantum Mechanics and Hard Drives Quantum mechanics is all around us. Most of the time, we are not aware…
