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.
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.
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.
Improved Performance with UASP
UASP is supported in Windows 8 andServer 2012. 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.
The StarTech.com Advantage
- 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
