Add four USB 3.0 ports with two independent channels, LP/SATA power, and
charging support to your PC through a PCI Express slot. The PEXUSB3S42V 4-Port
PCI Express USB 3.0 Card lets you add four USB 3.0 ports with two dedicated 5
Gbps channels to your PCIe x4-enabled PC. This independent port architecture
improves USB 3.0 performance by transferring data on two individual channels to
your computer, giving you faster file transfers.
When multiple devices are connected, traditional single bus USB 3.0 cards share
your maximum bandwidth between all ports. By employing a second host controller
chipset, the transmission channel is shared across two ports rather than four.
Dedicating up to 5 Gbps for each set of two ports reduces performance
bottlenecks, and effectively doubles your total available to bandwidth to 10
Gbps.
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.
For 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). 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.
The controller card is compliant with USB 3.0 standards while offering backward
compatibility with existing USB 2.0 / 1.1 devices. 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.
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.
