Over at CES, Jeff Ravencroft, 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.
The demo proved one thing: USB 3.0 is much faster than the current USB 2.0 protocol, a nearby display showing the one minute four second time necessary to move a 2.1 GB file from a notebook to an external hard drive under USB 3.0 as opposed to two minutes and seven seconds under USB 2.0.
Per CNET, the USB 3.0 standard is more power efficient than USB 2.0 “This uses one-third of the power it would take on USB 2.0,” said Ravencraft, in an interview at CES. “And it’s backward compatible,” he said, meaning it can also handle peripherals that use older USB standards.
On the peripherals friend, hard drive maker Western Digital has announced a new WD My Book based on the USB 3.0 specification with an adapter card, which will make an existing desktop PC USB 3.0-compatible.
Also, cards that go into a laptop’s ExpressCard slot are available, Ravencraft said. This allows an existing laptop to be upgraded to 3.0.
No official word has been made available as to when USB 3.0 ports and peripherals will arrive on Apple’s products.
