USB 2.0 vs. USB 3.0

Difference Between USB 2.0 and USB 3.0

USB 2.0 and USB 3.0 are two versions of the USB standard. USB means Universal Serial Bus and it has changed the way of communication between a computer and other gadgets like mice, keyboards, digital cameras, media players etc established today. This is a device invented by Ajay Bhatt. Its invention has replaced almost everything that was earlier used for this purpose. Although invented by for computers, USB has become so popular that it is used on virtually all electronic devices that are manufactured today. All game consoles, smartphones and PDA’s videos benefit from a USB power cord today. Even the Bluetooth devices and GPS chargers enjoy USB today. The huge popularity of USB can be found by its global sales of over 2 billion units in 2008. A striking feature of USB is that many of the same charge devices being connected with a computer.

For now there have been three versions of USB. USB 1.0 was released in 1996, USB 2.0 was born in 2000. It was in 2008 as USB 3.0 was introduced. Let us see the differences between USB 2.0 and USB 3.0.

Very high speeds

USB 3.0 is a major advance when we compare it with USB 2.0. The biggest difference is in how fast USB 3.0 can communicate with the host controller is a computer. The good thing about that is that it is backward compatible is that it can be used with USB 1.0 and USB 2. 0. For as USB 2.o had a top speed of 480 Mbps, which was considered sufficient in those days, now with the availability of devices with capacity of up to 64 gigabytes, it seems very slow. The data transfer devices with such huge capacity can take hours with USB 2. 0. The introduction of USB 3 .0 revolutionized the transfer of data between computers and devices with maximum transfer speeds of 4.8 Gbps is a huge improvement over previous speed. It is 10 times the speed that could be accomplished with USB 2.0


From the perspective of the use of power and demands, USB 3.0 is much greener compared to USB 2.0. USB 3.0 devices provide more power gadgets and retain power when the device is idling or loaded.

Better transfer rate with USB 3.0 enable devices with the help of high-frequency band as the act of Hi-definition video stream of possible. Digital video recorders have now found a perfect partner in the form of communicating with a USB 3.0 computer. With better performance and faster USB 3.0 devices leave other such as Bluetooth and e-SATA far behind. Although there are not many USB 3.0 devices out there, but with the Windows built-in Windows 7 and motherboard manufacturers providing a port here, there will be a day when USB 3.0 will become a symbol for the industry. The best thing about this is that it will be compatible with USB 2.0 and USB 1.0.
