LAS VEGAS--The president of the USB Implementers Forum discussed the arrival of USB 3.0 and gave a brief demonstration of transfer speeds on a Hewlett-Packard laptop at the Consumer Electronics Show.
In case anyone was in doubt, USB 3.0 is faster than the current 2.0 version. Below is a photo from CES of an Asus display, showing a comparison of the time it takes to drag a 2.1GB file from a laptop to an external hard disk drive using USB 2.0 and USB 3.0. (Asus was showing laptops with USB 3.0 connectors at CES.) And in the second video segment, Jeff Ravencraft, president of the USB Implementers Forum, provides a taste of the difference in transfer speeds between USB 2.0 and 3.0.
USB is more power efficient than 2.0. "This uses one-third of the power it would take on USB 2.0," Ravencraft said in an interview at CES. It's also backward compatible, he said, meaning it can also handle peripherals that use older USB standards.
