    Description
    Description

    Add 4 USB 3.0 ports to your desktop computer through a PCI Express expansion slot. The PEXUSB3S4 4-Port PCI Express SuperSpeed USB 3.0 Card (with SATA Power) adds 3 external USB 3.0 ports and an internal USB 3.0 port to any PCI Express-enabled computer system. With SuperSpeed USB 3.0, you can reach data transfer speeds up to 5 Gbps, while still being backward compatible with existing USB 2.0 devices at 480Mbps.

    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.

    With a built-in SATA power connector, each USB port can provide up to 900mA of power to USB 3.0 devices (500mA for USB 2.0) by connecting to your computer power supply. For added versatility, the controller card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.

    Backed by a StarTech.com 2-year warranty and free lifetime technical support.

    Improved Performance with UASP

    UASP is supported in Windows® 8, Server 2012 and Linux kernel 2.6.3 or later. 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.com add-on USB 3.0 cards, a UASP-enabled StarTech.com enclosure, and a SATA III solid state drive.
