Expand the number of available ports on your existing SuperSpeed USB 3.0 capable system. This USB 3.0 4-Port Hub is internally built upon the VIA VL810 Hub Controller, which is the industry's first integrated single chip hub solution that supports the higher transfer rates of the new USB 3.0 specification. Its one upstream port and four downstream ports support not just SuperSpeed transfer (5Gbps), but are also backwards compatible with previous USB specifications and offer support for Hi-Speed (480Mbps), Full-Speed (12Mbps), and Low-Speed (1.5Mbps) traffic. SuperSpeed USB not only makes transferring HD video files, high pixel count digital photos, and backing up hard drives quick and easy, but VIA's new hub controller allows consumers to get the most out of the technology by expanding the capacity of PC systems. Along with power management features that include the ability for devices to communicate latency tolerance to the host and for links to enter progressively lower power states when link partners are idle, the VIA VL810 is unique in that it is the first USB hub controller to use advanced 80nm CMOS technology, further lowering the chip's power usage.
