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,
8.1, Server 2012 and 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 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.
