USB 3.0 is the second major revision of the Universal Serial Bus (USB) standard for computer connectivity that offers data transfer rates of up to 5 Gbit/s, more than ten times as fast as the 480 Mbit/s top speed of USB 2.0. The USB 3.0 specification is similar to USB 2.0 but with many improvements.

In USB 3.0, dual-bus architecture is used to allow both USB 2.0 (Full Speed, Low Speed, or High Speed) and USB 3.0 (Super Speed) operations to take place simultaneously, thus providing backward compatibility. Connections are such that they also permit forward compatibility, that is, running USB 3.0 devices on USB 2.0 ports.

The USB 3.0 connector has a front row of four pins for the USB 1.x/2.0 backwards compatibility, and a second row of five pins for the new USB 3.0 connectivity.

This USB Mass Storage Device can transfer information faster if you connect it to a Super-Speed USB 3.0 port

The error message "This USB Mass Storage Device can transfer information faster if you connect it to a Super-Speed USB 3.0 port" can appear on a USB 3.0 system when a USB 3.0 device is connected properly to a USB 3.0 port. The error is commonly caused by the incorrect driver installed, certain cables wrongly specified as USB 3.0, order of starting equipment, equipment needing to be disconnected and reconnected, and overclocked computers.

USB 3.0 Devices when connected disrupt Bluetooth devices

USB 3.0 devices and cables may interfere with wireless devices operating in the 2.4 GHz ISM band. This may result in a drop in throughput or complete loss of response with Bluetooth and WiFi devices. Use a better quality shielded USB 3.0 cable.
