Following the delivery of final specifications for the SuperSpeed standard and a comprehensive review of the technology at a conference back in November, it is now being said that that a test-ready version of the USB 3.0 spec will be ready by the end of June. This will give computer and component makers a reference point for building hardware that supports the speedy new standard.
The next-generation USB 3.0, which is seen as one of the largest leaps in features for the standard, is expected to begin showing up in computers and peripheral devices by about this time next year with a theoretical maximum speed of 5Gbps - more than ten times what is offered by USB 2.0. The updated interface is also expected to reduce average power consumption while increasing the power output for devices that would otherwise require an AC adapter.
