What is USB 3.0 IN SHORT (kinda) -  Some of it’s most stand out features include it’s transfer rates, Physical appearance and power management. 

In terms of transfer rates, provides realistic transfer rates of around 3,200 Mbps or 3.2 Gbps. It introduces full duplex data transfer. Two of five lanes are reserved for transmitting data, while another pair is dedicated to receiving data, meaning that USB 3.0 can read and write data simultaneously at full speed. Previous USB specifications did not support bi-directional data transfer.

In the case of it’s physical appearance, what stands out most is the colour that you see as soon as you look. A USB 3.0 port usually has a light blue colour to show you that it is different than previous versions. This is what actually helps you know what you’re dealing with.

Finally in terms of it’s power management, USB 3.0 suspends device polling, which is replaced by interrupt-driven protocol. As a result, idle devices won’t experience a power drain since a signal from the device is required to initiate data transfer.

USB 3.0 in reality is an incredible faster and more efficient means of transferring data between devices. USB 3.0 is backwards compatible with USB 2.0. So whether you get a new USB 3.0 device or a new computer that supports USB 3.0, your old device will be able to communicate with the new interface. Naturally, it will do so at the old USB 2.0 speed. However, you won’t be able to use a USB 3.0 cable to connect a USB 2.0 device.
