StarTech.com 2 port PCI Express SuperSpeed USB 3.0 Card with UASP Support - 1 Internal 1 External PEXUSB3S11 User Manual

The PEXUSB3S11 PCI Express USB 3.0 Card lets you add one internal, and one external USB 3.0 port to your
PC through a PCI Express slot.

Featuring a native NEC PCI Express host controller chipset, the new USB 3.0 standard supports transfer rates
of up to 5Gbps, while still providing backward compatibility with older USB 2.0 (480Mbps) and 1.1 (12Mbps)
devices. The inclusion of an internal USB 3.0 connection provides the added benefit of compatibility with USB
3.0-based internal storage solutions or front-bay hubs.

Enhanced 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 

operating system). 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. See our UASP test results below for further
details.

For bus-powered USB devices, this PCIe USB 3.0 card includes an optional SATA power connector to connect
to your system power supply and deliver up to 900mA of power per port to USB 3.0 devices (500mA for USB
2.0).

Backed by a StarTech.com lifetime warranty and free lifetime technical support.

UASP is supported in Windows® 8, Server 2012 and 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 3.0 at peak performance.
