What are the Advanatges of USB 3.0 Over USB 2.0 Devices

We cannot think about a computer without having USB(Universal Serial Bus) ports because of the nonparallel use of them. Age of USB 2.0 is over and most of the computer systems and devices have started migrating to USB 3.0 standard. Though both standards are backward compatible, USB 3.0 connector is physically different from 2.0 connector due to additional pins. We can connect a Universal Serial Bus 3.0 device with  2.0 connector but then you can expect only Universal Serial Bus 2.0 performance. Here let us check the major advantages of USB 3.0 over USB 2.0 devices. Major advantages of 3.0 version over  2.0 are higher speed, better Power efficiency, better data buffering etc. Let us check the differences between these two standards one by one.

Differences Between USB 3.0 and USB 2.0

  1. Speed Difference Between USB 3.0 and USB 2.0

    Universal Serial Bus 3.0 is very much faster than  2.0. Data transfer speed of Universal Serial Bus 3.0 is about 4.8Gbps compared to 480 Mbps data transfer speed in 2.0 standard. So by comparing the difference in data transfer speed, we must say  3.0 is ten times faster than  2.0.

  2. Power Saving in USB 3.0 and USB 2.o Standards

    Power management of USB 3.0 is considerably better than in  2.0 standard. Universal Serial Bus 3.0 standard is capable to save energy when the system is in idle state. Technically speaking  2.0 uses power up to 500 mA and USB 3.0 uses up to 900 mA but the power efficiency of  3.0  standard is better than that in 2.0 standard.

  3. Duplex Settings in USB 3.0 and  2.0

    USB 2.0 devices can only handle one way traffic(half duplex) where  3.0 is able to send and receive data simultaneously(full duplex).

  4. Number of pins in USB 3.0 connector

    We cannot use USB 3.0 connector to connect 2.0 devices though the reverse is possible. It is because of the additional pins in Universal Serial Bus 3.0 connector. There are nine wires in Universal Serial Bus 3.0 connector cable and it is bigger compared to four wire  2.0 connector cable. USB 3.0 connector is physically bigger than  that of Universal Serial Bus 2.0 .

  5. Connector Colors Difference

    We can identify USB 2.0 connector and USB 3.0 connector by checking the color.  3.0 connector is big and blue where  2.0 connector is grey colored.
Here you have read the major differences between these two standards. We have seen the advantages of migrating from  2.0 to  3.0 standard. In case if you want to prevent users connecting Universal Serial Bus devices on your computer, just follow the instructions provided in the link below.
