Add 2 SuperSpeed USB 3.0 ports to your PCI Express-enabled PC. The PEXUSB3S25
2-Port PCI Express USB 3.0 Card lets you add two USB 3.0 ports to your PCI
Express-enabled computer system, with an optional 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).
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 is not supported by all operating systems).
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.
The PCIe USB 3.0 adapter is compliant with USB 3.0 standards for data transfer
speeds up to 5 Gbps, while still offering backward compatibility with existing
USB 2.0 / 1.1 devices. 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.
