What is a super speed USB 3.0 port?

USB 3.0 introduces a new operating speed called SuperSpeed. Compared to USB 2.0 bandwidth of 480 Mbps, SuperSpeed supports 5.0 Gbps making it 10 times faster than USB 2.0. USB 3.0 also supports lower operating speeds: high speed, full speed, and low speed.

Likewise, are USB 2.0 and 3.0 ports the same?

The A connectors still work properly so any 2.0 device with a 2.0 cable can be used with 3.0 ports or hubs. To sum up: USB 3.0 devices require 3.0 cables. USB 2.0 cables can be used with 3.0 ports but the transfer rate will fall back to 2.0.

What color are USB 2.0 ports?

Color is the key to telling the difference between USB 2.0 and 3.0 ports. In almost all cases, USB 3.0 ports are blue while USB 2.0 ports are black or white in color (see image below): Standard USB cables follow the same color scheme as well.
