USB 3.0 Specifications

By | January 9th, 2009



Yet another advancement in the Universal Serial Bus peripheral. The new USB 3.0 specifications are complete, and the products have started to be drafted, and will soon be available for consumer market. USB 3.0 is made to be more than 10 times faster than the current USB 2.0 standard.

The version 1.0 for the USB 3.0 is drafted and more research is underway for the fast development of this standard. The time line is as follows:

Few of the specifications of the USB 3.0 are:

1) The new SuperSpeed Bus giving maximum bandwidth of 5 Gb/s or 625 MB/s. The device can now work in four speeds, i.e. Low Speed, Full Speed, High Speed and Super Speed.

2) The Bus will work in full-duplex mode, giving concurrent input and output streams. Due to this, the cable signal count is increased from 2 in USB 2.0 to 6 in USB 3.0

3) The USB 3.0 is fully compatible with USB 2.0 connectors. However, USB3 new A and B receivers will have different plugs.

4) Use of Optical Fiber to achieve high speeds which are not possible with traditional copper wires.

5) 50% more power draw as compared to USB 2.0 on average.

6) Use of PCI Express 2.0 Bus Architecture.

Benefits:

1) Giving greater total bandwidth which will give fast data transfers specially suited for multimedia applications.

2) Giving more bandwidth then FireWire and HDMI ports, with lower cost of implementation. This might replace these connectors with USB 3.0

3) Specifically made for HD and streaming data. Thus, an HD movie can be watched through a device with USB 3.0 bus.

4) The Bus can be made to work as SATA II interface. Thus Hard Drives or Solid State Drives (SSDs) can be connected to the system using the USB 3.0 Bus at full SATA II speed of 300 MB/s

The new specifications will definitely be useful and more devices will be compatible with this Universal Serial Bus. The future of this bus architecture will be to replace all the interconnections with just only one USB interconnect. This new technology is surely going to make this happen soon.

    cool. informative

    You can not go wrong with 10X faster transfer speeds

    USB2 is great, but 10 times faster – has to be good.
    Of course with a higher power consumption, you will no doubt need to use a USB hub, or to have a higher rated power supply in a desktop or laptop.

    I think it will be a year or two before a lot of devices are readily available, and of course you will need a Motherboard that handles USB3.

    Well worth waiting for…
