VIA introduce USB2 Expressway Technology

VIA Labs, today announced its proprietary USB2Expressway Dedicated Bandwidth Technology for USB 3.0 Hubs which dramatically improves USB 2.0 performance when multiple devices are utilized. USB 3.0 Hubs featuring the technology eliminate USB 2.0 bandwidth limitations by providing full, dedicated bandwidth per port, allowing multiple USB 2.0 devices to be connected and operated at their maximum capabilities.

USB 2.0 provides 30-40MB/s of actual throughput, and this is shared across all connected devices. When multiple devices such as external hard drives, flash drives, and webcams are connected, they share available bandwidth which results in severely degraded performance. Compared to USB 2.0, USB 3.0 offers 10x more bandwidth and allows transfers as fast as 300-400MB/s. VIA USB2 Expressway Dedicated Bandwidth Technology allows USB 2.0 devices to utilize USB 3.0 bandwidth, eliminating bandwidth bottlenecks and freeing each connected device to reach its maximum performance potential.

“VIA Labs unveiled the world’s first USB 3.0 Hub at CES in 2010, introduced the VL811 second-generation USB 3.0 Hub controller with USB Battery Charging support in 2011, and for 2012, we are bringing true innovation in the form of USB2Expressway” said Terrance Shih, Product Manager, VIA Labs. “Even when copying files between two USB 2.0 drives, USB2Expressway can cut transfer times by 5x or more since we support simultaneous reading and writing of data. It breathes life back into your existing USB devices.”
