 As a result of having no moving mechanical parts, solid-state storage virtually eliminates the data access latencies present in electromechanical storage devices, and allows significantly higher rates of I/O operations per second (IOPS).Additionally, solid-state storage allows much faster sequential access to stored data, consumes less power, has better physical shock resistance, and produces less heat and no vibrations during operation.As a downside, solid-state storage devices have much higher per-megabyte prices than electromechanical storage devices, and generally come in significantly smaller per-device capacities.
