The new USB specification states lower power consumption and enhanced performance, while providing backward compatibility with billions of USB 2.0 enabled computers and peripheral devices currently in use. The specifications also state that data transfer rates have increased to up to ten times faster than Hi-Speed USB 2.0 standards. The SuperSpeed USB works at 5 Gigabits per second compared to the fastest speed of 480 Megabits per second offered by USB 2.0.
The USB 3.0 has analogous architecture to former versions of USB in that it is a cable bus sustaining data transfer between a host computer and a broad array of simultaneously accessible peripherals. The connected peripherals allocate bandwidth through a host-scheduled protocol. USB 3.0 employs dual-bus architecture to facilitate backward compatibility with USB 2.0. The USB 3.0 cables include eight primary conductors: three twisted signal pairs for USB data paths and a power pair. In addition to that are the twisted signal pair for USB 2.0 data path, two twisted signal pairs act as the SuperSpeed data path, one for the transmit path and one for the receiving path.
