The speed is quite high for a flash drive that costs as much as this one does. Even though it's a flash drive, the speed of an external SSD (solid-state drive) will almost probably be significantly higher. It is recommended that you get a silver model because after being inserted into the port, traces are left on the flash drive; however, these marks are less obvious on the silver model.
