USB 3.0 The Super Speedster As Connection Standard

Universal Serial Bus(USB), most popular connection standard between devices and a host controller (usually located on a computer).

USE: mice, keyboard, PDAs,flash drives, hard drives, headsets, speakers, TV tuners to webcams ,Game Consoles,cell phone connectors and chargers,GPS devices and bluetooth.
Till now we all were aware of USB 2.0 as connection standard and now we have new interface USB 3.0.

USB 2 had a maximum speed of 480 Mbps which is not good enough as our phone and PDAs that have a lot of internal storage built in take a long time.

USB 3.0 has a maximum transfer speed of 4.8 Gbps, almost 10 times faster than USB 2.0.
The USB 3 port on a motherboard is characterised by a blue color.

In 90s USB was designed to connect smart phones to PC's,Later it  became the standard for connecting any external devices.

Initially the transfer speed was few Mbps now it reached to Gbps due to an additional physical bus that is added in parallel with the existing USB 2.0 bus.
Also USB 3.0 utilizes a bi-directional data interface rather than USB 2.0's half-duplex arrangement, where data can only flow in one direction at a time.

So, what is the Biggest difference between USB 2.0 and 3.0?

USB 3.0 can communicate with computer's host controller 10 times faster than USB 2.0 ,speed upto 5 Gbps maintaining a backwards compatibility with USB 1.0 and 2.0.
Must say A better performer leaveing eSATA as well as Bluetooth protocols far behind.

How much Power USB 3.0 consumes?

USB 3.0 provides more power when needed to the device for maximum performance and conserve power when the device is connected but is idling.


I didn't realise different connections could deliver different amounts of power. Does that mean USB 3 would charge my phone faster.
