USB is most innovated ideas which causes revolution in field of computers,currently USB 2.0 is used in most of the computers which leads to a very high data transfer as compared to the older ones but now USB 3.0 is launched , next generation USB. USB 3.0 much faster and safe as compared to USB 2.0
New USB 3.0 products are 10 times faster than USB 2.0 means data transfer speed upto 5 GB/ sec
Faster power transfer (900 mA) in USB 3.0 as compared to USB 2.0 (just 500 mA) means increase in speed of scanning by USB scanner and other equipments.
It also means that LAN connection will be replaced by USB 3.0 as it is much faster than LAN.
But if you want actual speed of USB 3.0 than you have to use both USB 3.0 equipment and USB 3.0 ports, as in USB 2.0 ports, the speed of USB 3.0 equipments decreases and it will be same as USB 2.0 equipments or you can use the USB card adaptors as shown above.
USB 3.0 is a great improvement to USB 2.0. The biggest difference is the speed at which it can communicate with computer’s . USB 2 had a maximum speed of 480 Mbps, which was very speedy at its time but now it might not be enough because we now have USB flashdisk drives which are 64 GB in size, cell phone and PDAs that have a lot of internal storage built in, and even at 480 Mbps a full transfer of data in between devices can take a long time. So now USB 3.0 has a speed of 4.8 Gbps, almost 10 times faster than USB 2.0. Now if we want to transfer files from a pc to a 64 Gigabyte flashdisk to full capacity, we can do it in under 20 minutes!!
