Overview

A practical, high-performance upgrade solution

StarTech.com 's PEXUSB3S2EI controller card is a cost-effective upgrade that adds four USB 3.0 ports to your computer in one PCI-E slot. With two external and two internal USB 3.0 ports, your desktop or server will support a variety of USB 3.0 peripherals. The additional motherboard-style USB 3.0 connectors allow you to add further internal USB 3.0 devices to your PC. When your external connectors are taken, you can still plug in front-panel hubs or card readers using this versatile, cheaper alternative to motherboards and computer upgrades.

For added convenience, the card includes two external USB 3.0 ports so you can connect more devices, such as external hard drives or printers.

Flexibility and simplicity

Easy to install, the USB 3.0 card requires no additional drivers or software in native Windows 8.1 / 8 operating systems. What's more, its dual-format design is suitable for standard or space-saving cases, so it can always be adapted to your compact system if required.

This high-performance SuperSpeed USB 3.0 card supports transfer speeds of up to 5 Gb/s and the UASP protocol, which can increase read speed by 70% and write speed by 40% over traditional USB 3.0 when paired with a UASP-enabled enclosure. With its robust construction, the PEXUSB3S2EI provides reliable USB 3.0 connections.

Key features:

  • Flexibility to connect external and internal USB 3.0 devices with UASP support
  • Quick and easy configuration with native Windows 8 support
  • Suitable for standard or small footprint systems
  • Backwards compatibility means you can save money and plug in your existing USB 2.0 and 1.x devices
  • Transfer large files at lightning speed with support for up to 5 Gb/s data transfer rate

    No hardware sleep mode on the usb

    Relatively disappointed with this hardware installed on an asus P6tWS professional motherboard, indeed this system should allow me to connect a QNAP TR-004.
    However, the usb system does not allow for a USB-based standby mode when my server is switched off, so QNAP does not perceive that the PC is switched off and therefore does not put the disks into standby mode (so they run non-stop, which generates wear and tear and energy wastage...).
    Conclusion: functional product, speeds barely faster than a usb 2 on the motherboard which is a surprising test (carried out for my hard drives connected to USB and supporting USB3)
    Finally for any device that bases its standby on power from the USB ports, this product is not suitable.

    no problem

    I bought this card to add usb 3 ports to the back of a PC (all occupied) and to connect additional ports to the front panel as well

    instantly recognized by W10
    I have not tested the speed, but I don't see any difference with the original CM, so it's clear

    Basic, but effective

    Does exactly the job it is supposed to do, without any need for additional installation.

    Very stable without stalling and high performance

    Replaces on a motherboard the "Asus Asmedia" USB3 module that became unstable with the latest Win10 versions, even with driver updates.
    No more blocking when copying to external disk or USB data stick.
    Recognized immediately by Win10.
    The internal port allowed me to use the USB3 plugs of my case.
    Very satisfied.
