StarTech.com 2 Port PCIExpress USB 3.0 Card

Product Description

Add 2 USB (Universal Serial Bus) 3.0 ports to your desktop computer through a PCI Express expansion slot. The PEXUSB3S2 PCI Express USB (Universal Serial Bus) 3.0 card lets you add two USB (Universal Serial Bus) 3.0 ports to your PC through a PCI Express slot. Featuring a native NEC PCI Express host controller chipset, the USB (Universal Serial Bus) 3.0 standard supports transfer rates of up to 5 Gbps, while still providing backward compatibility for older USB (Universal Serial Bus) 2.0 (480 Mbps) & 1.1 (12 Mbps) devices. Enhanced with UASP support (USB Attached SCSI Protocol), this USB (Universal Serial Bus) 3.0 controller performs up to 70% faster than conventional USB (Universal Serial Bus) 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 (Universal Serial Bus) 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. In addition to providing a much faster transfer rate the PEXUSB3S2 USB (Universal Serial Bus) 3.0 card also supplies 900m A of power per USB (Universal Serial Bus) port, allowing more & more external devices to operate without the need of an additional power source. UASP is supported in Windows 8, Server 2012 & 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 (Universal Serial Bus) 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, Star Tech.com add-on USB (Universal Serial Bus) 3.0 cards, a UASP-enabled Star Tech.com enclosure, & a SATA III solid state drive.
