USB 3.0Also called SuperSpeed USB, USB 3.0 is the latest version of the Universal Serial Bus external bus standard that supports data transfer rates of up to and beyond 5GB/s (gigabytes per second). In addition to the increase in speed, UBS 3.0 is also optimized for low power and improved protocol efficiency. USB 3.0 ports and cabling will be a backward-compatible standard with previous USB technologies. USB 3.0 is not yet officially released. However, a prototype was introduced in late 2007 by Intel. The technology is also developed by HP, Microsoft Corporation, NEC Corporation, NXP Semiconductors and Texas Instruments. Products supporting USB 3.0 are expected to be released to consumers around 2009/2010.
