StarTech.com 4 Port PCI Express PCIe USB 3.0 Card w/ UASP - SATA Power
Add 4 external USB 3.0 ports to a low profile or standard computer, through PCI Express.
The PEXUSB3S4V PCI Express USB 3.0 Card (with SATA Power) adds 4
external USB 3.0 ports to any PCI Express-enabled computer system with
support for data rates up to 5 Gbps, while remaining backward compatible
with USB 2.0 / 1.x devices.
The card uses a "stacked" port layout that places the ports one on top
of the other, enabling all four USB 3.0 ports to be external facing,
while still allowing the card to fit into a small form factor/low
profile computer system using the included low profile bracket.
Plus, with a built-in SATA power connector, each USB port can provide up
to 900mA of power to devices that draw power from a host bus connection
(500mA for USB 2.0) by connecting to your computer power supply.
Backed by a StarTech.com 2-year warranty and free lifetime technical support.
USB 3.0 PCI-E card has 4 external USB 3.0 ports using a space-saving stacked layout
Time-saving file transfers, up to 70% faster than traditional USB 3.0 when used with a UASP-supported enclosure
Power high-powered USB devices as necessary, with the optional SATA power connector
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.
