StarTech.com 4 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter
W/ 4 Dedicated 5Gbps Channels - UASP - SATA / LP4 Power

Product Description

The PEXUSB3S44V 4-Port PCI Express USB (Universal Serial Bus) 3.0 Card lets you add four, dedicated 5 Gbps USB (Universal Serial Bus) 3.0 ports to your PCIe x 4-enabled PC. This independent port architecture improves USB (Universal Serial Bus) 3.0 performance by transferring data on four individual channels to your computer, giving you faster file transfers.\n\n When multiple devices are connected, traditional single bus USB (Universal Serial Bus) 3.0 cards share your maximum bandwidth between all ports. By employing four host controller chipsets, each port operates on a separate independent transmission channel. Dedicating up to 5 Gbps to each USB (Universal Serial Bus) port reduces performance bottlenecks, & effectively quadruples your total available to bandwidth to 20 Gbps.\n\n 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. See our UASP test results below for further details.\n\n For high-power USB (Universal Serial Bus) devices, this PCIe USB (Universal Serial Bus) 3.0 card

Includes:: an optional SATA or 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). The USB (Universal Serial Bus) 3.0 card also supports USB (Universal Serial Bus) Battery Charging

Specification 1.2 (Apple Mode only), letting you charge compatible Apple devices (iPhones & iPads) faster than a standard USB (Universal Serial Bus) 3.0 port.\n\n The controller card is compliant with USB (Universal Serial Bus) 3.0 standards while offering backward compatibility with existing USB (Universal Serial Bus) 2.0 / 1.1 devices. For added versatility, the USB (Universal Serial Bus) 3.0 PCIe card is equipped with a standard profile bracket &

Includes:: a low-profile/half-height bracket for installation in small form-factor computers.\n\n Backed by a Star Tech.com 2-year warranty & free lifetime technical support.\n\n Improved Performance with UASP\n UASP is supported in Windows&174; 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.\n\n At the same peak in testing, UASP also showed up to an 80% reduction in required processor resources.\n\n Test results were obtained using an Intel&174; 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.\n\n The Star Tech.com Advantage\n- Increase the efficiency of your USB (Universal Serial Bus) 3.0 devices with four dedicated bus channels & up to 5 Gbps of bandwidth per channel
