NOTE: Due to an error, some of the Xpand cards were shipped with the wrong driver CD. We have fixed this issue with all of the units we have in stock, but if you have issues you can find the correct drivers under the support tab on this page.

This product uses a SATA connector for power. If your computer has an older power supply that uses 4 pins then you might need this adapter.
Sewell’s Xpand USB 3.0 Host Card will expand your connection capabilities. It comes with 4 USB 3.0 ports, which allows you to take advantage of USB 3.0 technology with 4 devices simultaneously.

What’s so Great About USB 3.0?

Every year people seem to have greater demands for transferring larger files at faster speeds. It’s not just companies that need large file backups anymore. With the price of hard drives becoming more and more affordable, many at home now have external hard drives that are 1 terrabyte or larger. Not only that, but more people are now able to afford cameras that allow for high quality video and photos, making the files much larger. You need faster transfer rates. SuperSpeed USB 3.0 gives you transfer rates of up to 5 Gbps. That’s ten times faster than USB 2.0. Not only that, its bidirectional, letting you read and write data at the same time. What does that mean for you? It means you can download photos, music, videos, and data faster. But not just faster, ten times faster. And, if you want to upload something on your device, but it’s already downloading something else, you don’t have to wait. If you have some USB 2.0 devices, don’t worry, USB 3.0 is backward compatible, so it will still support all of your USB 2.0 and USB 1.1 devices. Just remember, if you want to achieve USB 3.0 speeds, you’ll need to make sure that your device (like your external hard drive) is compatible.

One more great thing about USB 3.0: It’s much friendlier on the environment and your wallet. USB 3.0 has new capabilities for managing power. These new capabilities allow for any unused devices you may have connected to your computer to enter into sleep mode, lowering your carbon footprint and your utility bills.


Up to 5 Gbps transfer rate through SuperSpeed USB 3.0. That’s 10 times faster than USB 2.0

1 out of 5 eggswould not work

Pros: none

Cons: Installed the card and downloaded drivers from vendors website. After installing drivers the card appeared to work but when I tried to access files from an attached ext drive, they were unavailable. When drive was attached to a USB port, they were accessible. Tried downloading newer drivers from VIA's website with same results

5 out of 5 eggsJust better than expected and cheap...

Pros: Cheap, i did put it in my old HP system running Win 8.1, no drivers needed it's working I hope that lasts for a while...

Cons: NO low profile adapter.

Other Thoughts: Be advise that you will need a SATA power connector NOT the normal 4 pin for IDE devices, so you probably want to be sure that you system has one available or buy one.
Mine came without disk but drivers are available in their site, however Win 8.1 just found it and installed the OS stocked drivers.

5 out of 5 eggsAmazing

Pros: This thing WORKS. Very fast, easy installation, Windows 8 support, Automatic installation.

Cons: Doesn't do my laundry.

Other Thoughts: Just got this last week, so I haven't tested it fully, but I plugged in four WD Black external drives and copied to/from all of them at the same time.
I tried copying to/from the Internal SSD, HDDs, across my 10Gb network, and the drives were screaming.
The data rates were WELL above 100MB/s consistently for each drive when copying medium-sized files, and it hit 600MB/s a few times when copying large files. Not bad, not bad at all.
Be sure you have a free SATA Power cable that will reach the back of the card.
