Add four USB Type-A ports with two independent 10Gbps channels to your computer, through a PCI Express slot. This USB 3.1 PCIe card lets you add four USB Type-A ports to your computer, through a PCI Express slot. With two independent 10Gbps channels, the card makes it easy to upgrade your PC to the faster speed of USB 3.1 Gen 2 so that you can access newer peripherals at twice the speed of traditional USB 3.0 (USB 3.1 Gen 1) cards.

When multiple devices are connected, traditional single-bus USB cards share your maximum bandwidth between all ports. By employing two host controller chipsets, shared across two ports rather than four, this 4-port USB 3.1 card dedicates up to 10Gbps for each set of two USB ports. It reduces performance bottlenecks and doubles your total available bandwidth to 20Gbps.

By adding 10Gbps USB ports to your computer, you can harness the speed of USB 3.1 Gen 2 and rest assured you're ready for both current and future high-bandwidth USB-A devices.

With higher data throughput support, this PCI Express USB 3.1 card is a necessity for external hard drives, hard drive enclosures, and many other USB 3.1 peripherals. Plus, the USB 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 3.1 bus-powered devices (500mA for USB 2.0). The card is ideal for use with large external storage solutions.

The 4-port USB 3.1 card features dual independent channels to your computer and shares 10Gbps of bandwidth between two USB ports.

Each set of two ports shares a combined bandwidth of 10Gbps. If a single device is accessing the channel, the card will provide data transfer rates of up to 10Gbps to the device. If two devices are accessing the channel simultaneously, the 10Gbps of bandwidth will be shared between both devices.

With four external USB-A ports you can connect more devices to your computer. The card provides easy access to commonly-used peripherals such as your flash drive and external hard drive and allows you to connect to both current and future high-bandwidth USB-A devices.

For more flexibility, you can couple the card with a USB-C to USB-A Cable (USB31AC1M) and connect your USB Type-C devices.

Connecting older peripherals isn't a problem. This versatile USB 3.1 Gen 2 (10Gbps) card is backward compatible with legacy USB 3.0/2.0 devices that use the common USB Type-A port, so you can eliminate the added expense and aggravation of purchasing new devices.

Rated 5 out of 5 by from Works great!There isn't much to say other than this product works exactly as you'd expect and no less. It's an excellent purchase to get an additional USB 3.1 ports on a desktop PC. I'm using all four ports with four USB hard drives with no issues and transfers are pretty fast on the USB 3 capable hard drives.I received this product in exchange for an unbiased review.

Rated 5 out of 5 by from Probably faster than your internal drives anyway!Theoretically, this card can pump through the full USB 3.1 speed to your USB3.1 external. If course, you have to have internal storage that can hit 10gbps or 1.25GBps to do that... My USB 3.1 dual MSATA RAID0 device comes close, but still doesn't max this card's ability. My internal storage didn't come close (and I don't have an 8 drive SSD RAID0 to test with (Startech, wanna help a tester out?!?!?) .The drivers worked fine in Windows. Didn't have to do anything in Ubuntu or CentOS, it just worked. No Mac tower to test with. Definitely add the external power to the card if you are using all 4 ports with devices drawing power. Inter-port transfers are faster than any device I had.So essentially, this device removed the USB interface as the bottleneck with storage. :)I received this product in exchange for an unbiased review

Rated 5 out of 5 by from Works on asus boards x299 boards onlyWorked out of the box easy on asus x299 board in any pcie slot but i changed to evga x299 dark board recently and i mainly use this card to connect 3 oculus sensor and headset usb with molex power connect and none of the connected devices are detected and if i connect more than 1 sensor at once i immediately get bsod and with windows default drivers or the drivers provided on this site dont work, for some reason evga board detects this x4 gen 2 when it is gen 3, i am not sure why and even evga tech had no idea and said its just incompatible, idk what else to do, but works great on asus x299 board though perfectly.

Rated 5 out of 5 by from Easy to install and does the jobRunning out of USB?Well, this product is for you then. This card is an easy product to install just like other Startech installs and great speed. I'm really enjoying to have it instead of the USB 2 and I can do data transfers with a full USB 3.1 speed and boot from one of my external drives as well.I tested with Windows 7, 10 and 2012 and I had no problems.Great work Startech!"I received this product in exchange for an unbiased review"

Rated 5 out of 5 by from Excellent speed easy Windows setupThis is a nice little USB 3.1 card for anyone needing to add a high speed card to a tower. I tried this card in 2 different machines under 2 different OS's and had some different results. For Starters I decided to try this in my older Mac Pro and hoped that it would work. I did not .. I should have paid more attention to the requirements as the newer OS's are not supported. which is a shame because this would be a great card in an old mac. However after some experimentation I decided to put this card into a PC and see what it was meant to do. I put this into my custom PC working off on older Z87 chipset and it worked beautifully with very fast speed and great performance. Installation is simple and easy and the driver had no issues. I tested the card with multiple hard drives and dedicated USB 3. drives had a really good performance. Older devices worked as expected. So in conclusion. The card works great in a PC. Not in a mac unless running older outdated software ( new drivers would be awesome for mac!!) but the card itself is good, simple and fastI received this product in exchange for an unbiased review.
