Universal Serial Bus (USB) is a way to establish communication between devices and a host controller (usually personal computers). As we all know, Today Generally we use USB 2.0 version of USB. The usage of this interface are so common ranging from peripherals such as mouse, keyboard, digital cameras, printers, personal media players, flash drives, and external hard drives. As Time changes the storage capacity has also changed from Gigabyte to Terabyte, Today data are in big gigantic size and to copy such file to portable hard drive may take plenty of valuable time. People felt the need for speed and demanding bandwidth is not just enough.
This is were USB 3.0 comes in picture , the Future of USB standard. USB 3.0 is the next major revision of the Universal Serial Bus. In 2007, Intel demonstrated SuperSpeed USB at the Intel Developer Forum. USB 3.0 specification was completed on November 17, 2008. As such, the USB Implementers Forum (USB-IF) has taken over managing the specifications and publishes the relevant technical documents necessary to allow the world of developers and hardware manufacturers to begin to develop products around the USB 3.0 protocol.
USB 3.0 promises the following:
- Higher transfer rates (up to 4.8 Gbps)
- Increased maximum bus power and increased device current draw to better accommodate power-hungry devices
- New power management features
- Full-duplex data transfers and support for new transfer types
- New connectors and cables for higher speed data transfer…although they are backwards compatible with USB 2.0 devices and computers (more on this later)
What is the difference in USB 2.0 and USB 3.0
Speed: USB 3.0 is 10X faster than USB 2.0. Theoretical Speed of USB 2.0 is 480 Mbps, while USB 3.0 can theoretically handle up to 5Gbps.
Power: USB 3.0 provides 50% to 80% more power when needed. The more hungry power devices could be directly powered through USB 3.0. At the same time USB 3.0 is also Power efficient, less power is used when needed.
Compatible: USB 3.0 is Backward compatible with USB 2.0. It can also be used with USB 2.0 Port and achieve USB 2.0 performance.
How can i connect USB 3.0 product on my Pc?
After reading this article you may be thinking that, how can i move on to USB 3.0. Many motherboard manufacturing company are now introducing USB 3.0 in their board. You can either Buy a new Motherboard or PCI-E Add on card. If you don’t want to spend money for new motherboard then its better you go with PCI-E add on card.
