StarTech.com 2 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter
With UASP - LP4 Power

Product Description

Add 2 Super Speed USB (Universal Serial Bus) 3.0 ports to your PCI Express-enabled PC. The PEXUSB3S25 2-Port PCI Express USB (Universal Serial Bus) 3.0 Card lets you add two USB (Universal Serial Bus) 3.0 ports to your PCI Express-enabled computer system, with an optional LP4 power connector to connect to your system power supply & deliver up to 900m A of power per port to USB (Universal Serial Bus) 3.0 bus-powered devices (500m A for USB (Universal Serial Bus) 2.0). 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 is not supported by all operating systems). 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. The PCIe USB (Universal Serial Bus) 3.0 adapter is compliant with USB (Universal Serial Bus) 3.0 standards for data transfer speeds up to 5 Gbps, while still offering backward compatibility with existing USB (Universal Serial Bus) 2.0 / 1.1 devices. For added versatility, the controller card is equipped with a standard profile bracket &

Includes:: a low-profile/half-height bracket for installation in small form-factor computers. 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.
