What is flash storage?

A storage device that stores persistent data on non-volatile solid-state memory chips. Unlike spinning electromechanical disks (i.e., hard disk drives), flash drives have no moving parts. Flash also typically produces no noise, stores and accesses data more quickly, has less latency, and is more reliable and durable than spinning media. Since the technology is more advanced, the cost of flash is usually higher although these costs are decreasing as production methods are refined, improved, and scaled.
