Microsoft throws support behind USB 3.0 with Windows 8

Microsoft is building a native USB 3.0 software stack for Windows 8, which could aid in competition against Thunderbolt

Microsoft is incorporating a software stack in its upcoming Windows 8 OS to natively support devices based on the USB 3.0 interconnect, which is in a battle for adoption with Intel’s Thunderbolt.

USB 3.0 is the successor to USB 2.0 standard and can transfer data 10 times faster between computers and external peripherals such as cameras and storage devices. Most laptops and desktops today come with USB 2.0 ports and many PC makers are offering USB 3.0 ports as an option. The current Windows 7 OS does not include native support for USB 3.0, but device makers offer drivers to ensure products are compatible with the OS.

Thunderbolt is based on copper wires, but ultimately will be based on optical technology. That will boost the interconnect’s transfer speed and distance, Intel has said.

“[USB 3.0] will still not be as fast as the Thunderbolt optic link, but copper never will be as fast as optics,” McGregor said.

Wireless charging could trump both USB 3.0 and Thunderbolt, provided it takes off, McGregor said. The transfer speeds may not be as fast, but device makers are showing interest in the technology, he said.

“It may eventually eliminate the need for peripheral connectors on mobile devices and then everyone will look to wireless interfaces,” McGregor said.

Other than enthusiast users, drivers aren’t something average PC users need to worry about, but native support for USB 3.0 in Windows 8 can’t hurt, said Nathan Brookwood [CQ], principal analyst at Insight 64.

“When they are talking about the history of Windows 8, they are going to be talking about the user interface and … touch,” Brookwood said.
“Thunderbolt will be one of many peripheral options available, just like IEEE1394 and Firewire, but I think USB will be the predominant interface because it is so heavily tied to the largest growth segment of the market, mobile devices, for both interconnectivity and power,” McGregor said.
