In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB 3.0 at peak performance.Īt the same peak in testing, UASP also showed up to an 80% reduction in required processor resources. UASP is supported in Windows® 8, 8.1, Server 2012 and Linux kernel 2.6.37 or later. For added versatility, the USB 3.0 PCIe card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.īacked by a 2-year warranty and free lifetime technical support. The controller card is compliant with USB 3.0 standards while offering backward compatibility with existing USB 2.0 / 1.1 devices. The USB 3.0 card also supports USB Battery Charging Specification 1.2 (Apple Mode only), letting you charge compatible Apple devices (iPhones and iPads) faster than a standard USB 3.0 port. See our UASP test results below for further details.įor high-power USB devices, this PCIe USB 3.0 card includes an optional SATA or LP4 power connector to connect to your system power supply and deliver up to 900mA of power per port to USB 3.0 bus-powered devices (500mA for USB 2.0). 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. Dedicating up to 5 Gbps to each USB port reduces performance bottlenecks, and effectively quadruples your total available to bandwidth to 20 Gbps.Įnhanced 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). By employing four host controller chipsets, each port operates on a separate independent transmission channel. When multiple devices are connected, traditional single bus USB 3.0 cards share your maximum bandwidth between all ports. This independent port architecture improves USB 3.0 performance by transferring data on four individual channels to your computer, giving you faster file transfers. The PEXUSB3S44V 4-Port PCI Express USB 3.0 Card lets you add four, dedicated 5 Gbps USB 3.0 ports to your PCIe x4-enabled PC.
