Windows 8 Will have USB 3.0, Microsoft Confims

Microsoft has officially confirmed at Building Windows 8 blog that Windows 8 will support USB 3.0 for faster performance.

Here is what the official announcement says:

One of the important roles Windows plays as part of a broad ecosystem is developing support for new hardware. This is a pretty involved process and so for this post we wanted to take a look at supporting USB 3.0, something we know everyone is anxious to be using because of the improvements it brings.

With throughput up to 10 times faster than USB 2.0 and improved power management that results in longer battery life, USB 3.0 introduces compelling reasons to improve the world’s most popular PC interface. By 2015, all new PCs are expected to offer USB 3.0 ports, and over 2 billion new “SuperSpeed” USB devices will be sold in that year alone.

The decision to invest in USB 3.0 was an easy one to make, but doing so without compromising the existing USB ecosystem was a big challenge to overcome. Our design had to follow the revised 3.0 specification precisely in order to enable emerging USB 3.0 hardware. There are also billions of older USB devices that Windows must remain compatible with.

USB 3.0 includes a new host controller and defined the new “SuperSpeed” USB device (5 Gbps). Together, the controller and device could operate at theoretical speeds of up to 10 times faster than USB 2.0. With this new standard, you’d be able to copy a high definition movie from a USB storage drive in about 80 seconds instead of the 15 minutes it takes with USB 2.0. The specification also introduced a new transfer type —streams — which allows the storage drives to process reads and writes more efficiently.

The new specification provided 80% more power than USB 2.0. This meant faster charging and removed the need for odd “Y” cables used by external DVD drives and other high power devices. But charging isn’t the only power consideration. With mobile computing, people want PCs that conserve battery life. By also introducing new low power states, finishing tasks more quickly, and powering down at every opportunity, USB 3.0 is more power efficient than its predecessors. This translates to longer battery life for notebooks and less power consumption for desktops.

Most importantly, the specification promises to enable a new generation of USB while maintaining compatibility with full, low, and high speed devices. Even the plugs are backwards compatible.

Perhaps the most important aspect of USB 3.0 is the expectation that customers have of USB: it’s just USB3 so it should just work, right? Each and every USB device, low, full, high, and SuperSpeed, has to work in Windows 8. That’s our focus while also delivering the most robust and reliable USB stack.

  1. Lets be serious. Microsoft is too soft. Investors wonder why Microsoft stock just floundered years, while new companies and Google had so much success.

    Oracle stock ran from 15 to 35 during the past five years.

    Google stock ran from 380 to over 700 during the five year period

    Microsoft stock traded from 28.84 DOWN to a current price of 25 during the five years and was 30 ten years ago. One of the few real tech companies to go nowhere.

    Why? Microsoft is too soft. Their executives are soft as compared to associates and executives at Google, Oracle and other successful competitors that steal their secrets . . . build their own companies . . . and then sell them to Microsoft! I know. My brother-in-law, Peter Leonard, is an Project Manager at Microsoft, so I’ve seen first hand just how soft and lazy these guys can get, not to mention the “who cares” attitude. Or talking too much and dragging projects out so long, that the competition is ready to go to market by the time Microsoft is ready to go to Beta.

    All Microsoft execs and managers care about is a cushy job, nice dining room with great benefits and tons of time off. And when they don’t get enough time off, they create it. Yes, I kid you not, they create time off hours off and fun time. They have the benefits of working at home . . . or from a beach in the Islands or anywhere they please, as long as there is a phone and an Internet connection. Believe me, I’ve been on those trips when he was “working” on the beach, in the pool, sipping pina coladas and enjoying the life of leisure.

    If Larry Ellison caught one of his executives on a “working” day like this, he’d probably hang him from the top floor of the Oracle Building or from the mast of his sailing yacht, maybe even drag him behind the yacht as shark bait. But when he is really on the ball, he finds them a job at Microsoft.

    Look at all the time Microsoft has had to catch Google with a Search Engine. Their first attempt failed miserably. Second attempt was to buy Yahoo, but Ballmer bungled that with an ego as big as his head, and probably a hundred execs and managers below him advising him . . . we can do it better. How? On the beach? At home? In the hot tub? Now they have Bing. Well, Bing This, because Bing is a complete failure because of guys like my brother-in-law who are there for the benefits, and not willing to take any chances or come up with anything new that might rock the boat of their executives that care more about the security of their positions than the guys and gals below them.

    They talk about things they should not be talking about, so the competition can either leap frog them or incorporate their good ideas into their development, and avoid the mistakes made at Microsoft. I’ve heard things I should not have heard, so I’m sure others have. If you can’t keep your trap shut at Microsoft, you’ve got problems.

    So my advice to Steve Ballmer is to go out and hire as many Googlers as you can and start canning your army of drones, even if that means a short set back in Microsoft plans. Why? Because sooner or later, Microsoft will go the way of Sears, IBM, Kmart and others that refused to kick their managers and executives in the butt or out the door.
