2 Port SuperSpeed USB 3.0 PCI Express Card with
UASP - SATA Power

Product ID: PEXUSB3S22

The PEXUSB3S22 2-Port PCI Express SuperSpeed USB 3.0 Card (with SATA Power) lets you add 2 USB

3.0 ports to any PCI Express-enabled computer system. With SuperSpeed USB 3.0, you can reach data

transfer speeds up to 5 Gbps, while still being backward compatible with existing USB 2.0 devices at

480Mbps.

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 UASP supported enclosure (Note: UASP requires a

compatible 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.

With a built-in SATA power connector, each USB port can deliver up to 900mA of power to USB 3.0

devices (500mA for USB 2.0), by connecting to your computer power supply. For added versatility, the

controller card is equipped with a standard profile bracket and includes a low-profile/half-height bracket

for installation in small form-factor computers.

Backed by a StarTech.com 2-year warranty and free lifetime technical support.

Improved Performance with UASP

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.

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, StarTech.com add-on USB 3.0

cards, a UASP-enabled StarTech.com enclosure,

and a SATA III solid state drive.
