Startech 4 Port Pcie Usb 3.0 Card

Startech 4 Port Pcie Pcie Usb 3.0 Card Green,Silver . Boost your PC´s connectivity with the StarTech 4-Port PCIe USB 3.0 Card. This component adds four high-speed external USB 3.0 ports, supporting up to 5Gbps, with seamless backward compatibility for older devices. Experience significantly faster data transfers, up to 70% quicker, thanks to UASP support when paired with compatible enclosures and operating systems. The card features a space-saving stacked design and includes a low-profile bracket for smaller systems. Its integrated SATA power connector ensures each port delivers ample power to connected devices. The PEXUSB3S4V PCI Express USB 3.0 Card (with SATA Power) adds 4 external USB 3.0 ports to any PCI Express-enabled computer system with support for data rates up to 5 Gbps, while remaining backward compatible with USB 2.0 / 1.x devices.Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure (Note:UASP requires a compatible operating system).Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers.See our UASP test results below for further details.The card uses a stacked port layout that places the ports one on top of the other, enabling all four USB 3.0 ports to be external facing, while still allowing the card to fit into a small form factor/low profile computer system using the included low profile bracket.Plus, with a built-in SATA power connector, each USB port can provide up to 900mA of power to devices that draw power from a host bus connection (500mA for USB 2.0) by connecting to your computer power supply.Improved Performance with UASP.UASP is supported in Windows® 8 and Server 2012.In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB 3.0 at peak performance.At the same peak in testing, UASP also showed up to an 80% reduction in required processor resources.Test results were obtained using an Intel® Ivy Bridge system, StarTech add-on USB 3.0 cards, a UASP-enabled StarTech enclosure, and a SATA III solid state drive. tradeinn Techinn
