SuperSpeed USB 3.0 Has Ben Unleashed

3.0 Version of the Universal Serial Bus specification has been released.On Monday Unveiled by the USB Implementers Forum, the latest USB 3.0 can support data-transfer speeds of up to 4.8Gbps — 10 times the speed provided by the previous version USB 2.0.The new standard, USB, is also expected to be more power-efficient than its predecessor. therefore it is also called as ” SuperSpeed ” , Obviously because of its high speed performance“SuperSpeed USB is the next advancement in ubiquitous technology,” Jeff Ravencraft, the president of the USB Implementers Forum (USB-IF), the industry group that promotes USB technology, said in a statement on Monday. “Today’s consumers are using rich media and large digital files that need to be easily and quickly transferred from PCs to devices and vice versa. SuperSpeed USB meets the needs of everyone, from the tech-savvy executive to the average home user.”There is a thinking from the USB-IF that they hopes that USB 3.0 will be built into computers from late 2009, , roughly a decade after USB 2.0 made its appearance. According to the industry group, the first such products will include external hard drives, flash drives, digital cameras and personal media players.

New Usb 3.0 was designed to be backwards-compatible with earlier iterations of USB

Companies that were instrumental in developing USB 3.0 include Intel, HP, Microsoft, ST-NXP Wireless, NEC and Texas Instruments. Intel had taken the lead in the specification’s development, but only made a draft specification available to companies such as AMD and Nvidia in August of this year. Prior to that release, there had been concerns that the USB 3.0 specification would be forked into divergent versions.USB 3.0 are compatible with USB 2.0 device plugs for the respective physical form factors. However, only USB 2.0 Standard-A receptacles can accept USB 3.0 Standard-A device plugs.SuperSpeed protocols are supported via 4 extra wires for dedicated SuperSpeed transfers. Protocol supports full-duplex data transfers. Include support of idle, sleep and suspend states, as well as link and function-level power management are the New power management features
