Two screens, one for USB 2.0 and one for USB 3.0; the 3.0 version is speedier. Various advantages: Quick, adorably diminutive, and stunning. It should be noted that the read speed in port 3.0 is really faster than indicated. Various disadvantages: Even though it becomes warm, it can still be used as a flash drive with Windows in an emergency.
