Overview

The PEXUSB3S400 PCI Express USB 3.0 Card adds 4 independent external USB 3.0 ports to any PCI Express x4-enabled computer system, with full bandwidth support (up to 5Gbps) per port when connected to USB 3.0 devices.Unlike other USB 3.0 cards, which share the maximum bandwidth between multiple ports, the card offers maximum transfer rates to each device when multiple devices are connected.

Further 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.

This 4-port USB 3.0 card features a stacked port layout, which places the ports one on top of the other, so more ports are able to fit into a smaller space. 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, 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.

UASP Speed Diagram

At the same peak in testing, UASP also showed up to an 80% reduction in required processor resources.

UASP Speed Diagram

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

  • Increase efficiency of your USB 3.0 devices with up to 5 Gbps of bandwidth on each port
  • 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

Applications

  • Upgrade an older PCIe-based system with USB 3.0 connectivity, to fully utilize USB 3.0 devices
  • Expand a system's USB capabilities with four additional external USB ports, for connecting additional external hard drives, CD/DVD drives, MP3 players, printers, scanners, webcams, game controllers, digital cameras, etc.
