[+] Hands-on Look At USB 3.0, Spec Details Revealed 251 comments
notdagreatbrain writes "Maximum PC dug up some new information about USB 3.0, got their hands on the new connectors, and even took a look inside the new cables. They learned several new details about the next-gen version of the ubiquitous interface. USB Superspeed will be backward compatible with USB 2.0. The maximum speed of the new spec is 4.8Gbps, which is ten times faster than hi-speed. Five new wires are bundled in the cable, four of them used for data transfer (bi-directional transfer is now supported). More power will also be funneled through the line, so you can charge more devices, faster. The wireless USB is also getting upgraded to version 1.1, and will include ultra-wide band frequency support and Near Field Communication for near-instant swipe-based syncing."

    Does USB 3.0 assist in the more rapid delivery of porn to my PC?

    If the answer is "Yes", then please continue with your announcement.

    Still the same symmetrical plug design....stupid, stupid move. Would have been that hard to add a ridge on one side or something, so you don't have to stare at the end??

      yea we know its but here are the reasons its needed 1) Backwards compatible 2) Fit more ports in a smaller area, less wasted space 3) Cheaper for manufactures because the mounts are the same thus making it a cheaper industry upgrade to adopt.

      Yes, the USB connector is blind accessible. The "top" of the A plug's plastic part is supposed to be embossed with a USB logo, and the "bottom" isn't supposed to be embossed. So if you know which way is "up" on your PC's connector, or if you are using a hub (in which case up is more obvious), you can more easily plug them in blind.

        The problem is that the host-connector has no markings, and sometimes "up" might be either left, right, up or down relative the up of the device itself.

        What they should have done, from the beginning of USB, was to have the connector truly symmetric, so that you could plug it in either way.

      Most UBB connectors have a USB symbol on one side which means (this side up). I'd never really thought about this until someone gave me an iPod. I then found that I was forever struggling to get the connector in.

      What I concluded was happening was:

      1. I'd sub-consciously worked out that the connector is inserted USB symbol up.
      2. The Apple USB connector has the USB symbol on, but on the other side it has an Apple symbol.
      3. My sub-conscious was in fact not distinguishing between USB symbol and Apple symbol. Instead the logic was something like, "that side has a symbol on, I'll put it facing upwards".

      I'm quite sure that the "symbol faces up" convention is a part of the USB spec. I never needed to know this because my brain naturally worked it out without it ever entering my consciousness. This is a truly wonderful piece of human interface design and yet those morons from Apple go and break it with an inane piece of branding. Way to go Apple. Anyone who ever thinks that Apple cares about usability should think again.

      If it takes you more than two tries to put in a USB plug, you probably shouldn't be allowed near a computer anyway.

        Never had this:

        Try the correct way.
        Try the other way.
        Try the correct way again.
        Look at plug
        Insert screwdriver to bend plug back into shape
        Try the correct way.

    I'm certain that USB3 will be "supposed to be" backward with USB 1; 1.1; 2, but will likely only be backwards compatible with 2. Right now, a Hard disk cannot keep up with eSATA at 1.5 Gb/s, nevermind eSATA at 3Gb/s. For the past year or so, many of us have been buying $15 eSATA cards for our old computers, and new computers with eSATA built in. Considering that external HD cases with eSATA connectors cost only about $16 (something with 4 eggs, at Newegg) what is the benefit?

    Possible benefits would be increased transfer speed to peripheral devices, but can we reasonably expect devices that fast by then? Personally, I would hope that 10Gb/s ethernet would come down in price by then. The only real benefit I see with the proposed USB3 is something for a processor core to do....

    $.02

    PS: I will give a possible something to do mention to Hard Disk (Solid-State) video recorders... but they could use eSATA as well & still be saturated..

      simple answer: yes

      Complicated answer:
      Progress is inevitable and we definitely need that kind of speed. Its not only about hard drives but also about Audio visual components. Such as an USB HDTV Dongle which is a bit slow for USB 2.0. It is also one of the reasons why webcams currently max out at 2.0 megapixels. anything more than that the current USB 2.0 cannot handle. It is quite easy to eat through those 600MB/s, Just think of the USB 3.0 replacing 1000mbit ethernet.

        It's not a huge limitation for USB since devices just include a USB host controller as well. This allows, for example, a USB camera to print to a USB printer. The main win for FireWire is the lower protocol overhead (meaning that it gets closer to the rated wire speed) and the lower CPU usage.
