Microsoft’s Director of Program Management for the Devices and Networking group, David Flanagan recently talked about the native support of the USB 3.0 standard on Windows 8 on the Building Windows 8 (B8) MSDN blog.
According to Flanagan, support of the USB 3.0 standard changes a lot of things for the better and it’s not just limited to the increased speed.
USB 3.0 on Windows 8 To Bring Better Battery Life, Says Microsoft on B8 Blog
According toe Flanagan, all new PC’s and portables are going to come with USB 3.0 as standard issue by 2015 and over 2 billion ‘SuperSpeed’ USB devices will sell that year. They really wanted to adopt USB 3.0 as soon, said he, and the challenge was to make sure that the integration did not compromise on the existing USB framework.
However, that is all behind them now and they have successfully made Windows 8 completely ready for USB 3.0. Other than the 5Gbits per second speed, the other great feature of this upgrade is better power management. The new standard has made efforts to curtail power consumption, thereby improving battery life on laptops and other portables.
Even though it uses less power than older USB standards, USB 3.0 also passes on more power to connected devices. About 80% more power at that. This will make for faster charging of connected devices.
Microsoft Still Has To Deal With Older USB Devices On Windows 8
There are approximately 10 billion devices that are built with specifications lower than USB 3.0. Microsoft has to make sure that these devices work properly with Windows 8 right along side USB 3.0. Good thing about USB 3.0 is that it not only has a transfer rate of 5Gbits per second (compared to the 12 Mbps of USB 1.0 and 480Mbps of USB 2.0) it also supports devices running older versions. This has made it somewhat easier to implement for companies like Microsoft who have to deal with a large number of legacy devices.
