4 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter w/ 4 Dedicated 5Gbps ChannelsView larger Add four USB 3.0 ports with four independent channels, LP/SATA power, and charging support to your PC through a PCI Express slot The PEXUSB3S44V 4-Port PCI Express USB 3.0 Card lets you add four, dedicated 5 Gbps USB 3.0 ports to your PCIe x4-enabled PC. This independent port architecture improves USB 3.0 performance by transferring data on four individual channels to your computer, giving you faster file transfers. Increase the efficiency of your USB 3.0 devices with four dedicated bus channels When multiple devices are connected, traditional single bus USB 3.0 cards share your maximum bandwidth between all ports. By employing four host controller chipsets, each port operates on a separate independent transmission channel. Dedicating up to 5 Gbps to each USB port reduces performance bottlenecks, and effectively quadruples your total available to bandwidth to 20 Gbps. Power high-powered USB devices as necessary, with the optional LP4 or SATA power connector For high-power USB devices, this PCIe USB 3.0 card includes an optional SATA or LP4 power connector to connect to your system power supply and deliver up to 900mA of power per port to USB 3.0 bus-powered devices (500mA for USB 2.0). Write / read speed comparisonView larger Improved Performance with UASP In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB 3.0 at peak performance. CPU utilization comparisonView larger UASP is supported in Windows 8, 8.1, Server 2012 and Linux kernel 2.6.37 or later. At the same peak in testing, UASP also showed up to an 80% reduction in required processor resources. *Note: Test results were obtained using an Intel Ivy Bridge system, StarTech. com add-on USB 3.0 cards, a UASP-enabled StarTech. com enclosure, and a SATA III solid state drive. View larger Supports USB Battery Charging Specification 1.2 (Apple Mode only) The USB 3.0 card also supports USB Battery Charging Specification 1.2 (Apple Mode only), letting you charge compatible Apple devices (iPhones and iPads) faster than a standard USB 3.0 port. View larger PCIe x4 interface compliant with PCI Express 2.0 specifications Upgrade an older PCIe-based system to USB 3.0 connectivity and UASP support to fully utilize USB 3.0 devices View larger Includes a Low Profile/half-height installation bracket For added versatility, the USB 3.0 PCIe card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.
