SuperSpeed USB Devices ( USB 3.0) will appear only in a year. According to (Jeff ravencraft), which heads the USB 3.0 Promoter group, the works on USB 3.0 creation is going according to previous plan. The specification 1.0 version , as it is expected, will be accepted in the third or fourth quarter of the present year, and the deliveries of products with the new interface support will begin in the second quarter 2009.
USB 3.0 Interface is compatible with its predecessors, it is capable to transmit data with speed up to 5 Gbit/s. This even exceeds the possibilities of SATA II interface (3 Gbit/s). In this case, SuperSpeed USB will become, in first place, interface for high-speed connection of solid-state disk.
Important merit of USB 3.0 is the lowered energy consumption, achieved due to the failure of protocol with the regular interrogations in favor of interrupts. For data transmission USB 3.0 will use two pairs of conductors. The maximum length of cables will be three meters.
