2.0 Versus 3.0

The name USB 3.0 docking station alone gives us the idea of a difference. You may wonder, what would then be the difference of a USB 2.0 docking station to a 3.0 one? Is there really a huge difference between a 2.0 and 3.0 USB?
2.0 Versus 3.0 - Image 1
Background
USB 2.0 was released in April 2000 while USB 3.0 was released in November 2008, eight years after the release of the 2.0 version. In terms of speed, the 2.O version has the speed of 40 Mbps it is considered a high speed. For signaling method, either sending or receiving data can be possible for polling mechanism. It is not possible to use both function. The 3.0 version can do both at the same time. Number of cable wires for the initial version is four but the later version is up to 9.
Physical Differences
The two versions are carrying different colors for connectors; the color gray is used for the 2.0 version while blue is used for the 3.0 version. The difference in colors helps easily identify the two versions. In terms of cable length, the 3.0 version is 2 meters shorter than the 2.0 versionâs 5-meter length. This helped in lessening unnecessary length that can be a waste. Metal contact also varies. 3.0 used a 9pin metal as opposed to the 4pin metal used for the 2.0 version.
Backward Compatibility: What is It?

This simple means that the higher version can be used by the lower version but with limitations. A 3.0 device would only work as a 2.0 device in terms of speed and capability. The speed 3.0 boasts of cannot be utilized here. The two versions are compatible depending on the peripherals used. A 2.0 version device plug can use a 3.0 receptacle provided that the two physically match. However, not all 3.0 receptacles accept 2.0 devices because they may not fit. There is a discrepancy in terms of size.

Why USB 3.0 Wins and Why You Should Convert
The most important reason for switching to updated version is the speed it provides. It is said to be faster than its predecessor. 10 times faster in fact. A USB 3.0 docking station stand would also add to the convenience this technology offers since all peripherals would be easily connected. Though it is considered relatively expensive, it is a good investment for faster connection that can go up to 5 gigabits per second that is slower than 2.0âs 480 Mbps.
