![]() Additional wires require more space in both the cables and connectors, so there are new types of connectors for the B Male and Micro B Male. The second main difference is the addition of another physical bus - doubling the amount of wires, from 4 to 8. Note that the transfer speeds also depend on the device in use in addition to the bus type and USB ports and cables. First the transfer rates: USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer rates of 4.8 Gbps - that's 10 times faster. When comparing 2.0 and 3.0 there are a few major differences. What is the difference between USB 2.0 and USB 3.0? Additional devices like memory card readers, display adapters, and transfer cables launched in 2011, with more products expected in 2012 and later. ![]() Currently the majority of 3.0 devices include external hard drives, hard drive docks and flash drives. USB 3.0 cables and devices are also required to achieve the fast USB 3.0 transfer speeds. PC computers and laptops have slowly been implementing the new standard since 2010, but the new 3.0 ports are expected to be in the majority of all new computers by 2012 when the popular manufacturers make it a standard. Hubs followed allowing additional 3.0 expansion. Implementation of the technology began in 2009 initially with USB 3.0 adapters (PCIe and ExpressCard) to allow installation of the new 3.0 ports into current computer systems. This new standard offers increased transfer rates up to 4.8Gbps, increased maximum bus power, improved power management, and new connectors and cables that facilitate the higher transfer speeds and additional power. ![]() USB 3.0 is the latest revision of the Universal Serial Bus standard released in 2008.
