The PEXUSB3S24 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 SATA 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. See our UASP test results below for further details. 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. Backed by a Star Tech.com 2-year warranty & free lifetime technical support. enhanced Performance with UASP UASP is supported in Windows 8, 8.1, Server 2012 & Linux kernel 2.6.37 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. 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. The Star Tech.com Advantage Increase efficiency of your USB (Universal Serial Bus) 3.0 devices with up to 5 Gbps of bandwidth Fits into full or low profile/small form factor (SFF) systems, with a dual profile design Power high-powered USB (Universal Serial Bus) devices as necessary, with the optional SATA power connector
