4 out of 5 eggsOK Product

Pros: Good connection speeds. Extended the life of a older (core 2 generation) computer

Cons: Bracket isn't 100% square with the case. Bending the bracket helped in my case but the rear of PCIe connector is still pulled out a little instead of sitting completely in the socket. It appears to be making electrical connection so I guess it's OK.

Depending upon how well made your case is, that bit of pull out may result in the electrical disconnection.

Other Thoughts: Is low profile capable but does NOT come with low profile bracket.

Drivers should gotten from TI's website for the latest and greatest. It's a TUSB7340 chip

I will probably take a Dremel to the top screw hole to fix this alignment issue. This is misaligned just enough to make me feel uncomfortable...

4 out of 5 eggsgood card, wrong driver disk

Pros: Allows for me to use the USB 3.0 ports on the front of my case. Sees to work alright. 2 extra USB ports on the back as well

Cons: Driver disk that was supplied did not include the proper driver, had to do some digging online to find it. Requires 12v power which I'm short on leads for.

Other Thoughts: Connectors lie flat so I could squeeze it into a tight space in my already crowded case. Could be better if the right drivers were included on the disk.

5 out of 5 eggsUSB 3 in my WHS2011 server now

Pros: Upgrading the case to my Windows Home Server 2011 PC that had USB 3.0 ports on it. My server mother board, ASRock A55M-HSV does not have USB 3.0 support, front or rear. Picked up this card specifically because another user said it worked in his WHS2011 box, and it works for mine too! Used the included CD to install the drivers, server detected card but didn't find a driver for it, CD install worked great. Now I have USB header for my new case, plus two USB 3 ports out the rear for my external USB 3 backup drives for the server.

Cons: None

Other Thoughts: Transferred a 4 GB file from a WD Elements 1 TB USB 3 drive to the server and averaged 104 MB/s, transferred back to different folder on the drive and averaged 150 MB/s, same results for every port.

Manufacturers website says you will not get advertised speed if you install the card in a PCIe 1.0 x1 slot, advertised speed is only obtainable in a PCIe 2.0 x1 slot, which my mobo has. Claims typical speed for the PCIe 1.0 x1 slot is ~61 MB/s vs. ~117 MB/s on PCIe 2.0 x1 slot.

5 out of 5 eggsJust what the doctor ordered

Pros: - Very simple installation.

- Drivers on CD actually worked.

- Actually works at USB 3 throughput.

Cons: Doesn't tuck me into bed at night.

Other Thoughts: Kidding aside, I installed this expansion card onto an older motherboard to make use of the front panel USB 3. Everything works, even double checked to make sure unplugging devices did not hang the system. Can't really ask for more when everything works as it should.

5 out of 5 eggsRuns Great

Pros: It works well with the latest driver sllc423e from TI.

Cons: Had to bend the bracket slightly but this is nothing unusual. Had to buy a sata power extension cable.

Other Thoughts: I downloaded HD SPEED software to test the read/write speeds and compared using usb 3.0 port to usb 2.0 port.

4 out of 5 eggsWorks

Pros: Works Great, makes my thumb drives operate faster than they do on USB 2.0 ports. My Corsair 200R case front USB 3.0 connectors work now. Device recognition is very fast.

Cons: Had to modify my SATA power connector to accommodate the edge of the PCB since the plug is mounted back just a little bit.

Other Thoughts: Works great, haven't had any issues. Wish my ASUS M5A97 LE mobo had the 20 pin USB 3.0 connector on it.

1 out of 5 eggsNo driver for linux - Misleading specs

Pros: Works at USB2 speed

Cons: I selected this driver because the product description specifically said that this USB3 card worked in Linux. This is simply NOT TRUE. There is no driver for Linux in the CD and nowhere where to download a Linux driver. The card itself comes in a package that features another unknown brand. Further research shows that the Texas Instruments chip used to build that card does not support Linux: [104c:8241] (rev 02)

Other Thoughts: Please do not lie. Our time and jobs are on the line. I recommend that readers not buy from this brand. We should all boycott the companies that lie to us.

4 out of 5 eggs

Pros: It works. It's reading everything I plug into it so far (iPad, iPhone, thumb drives, wireless receiver for mouse keyboard)

Cons: After fixing my driver issue; no cons right now. Didn't really test the speeds.

Other Thoughts: I had some issues with this initially. Whenever I would unplug a device; this controller would be unresponsive. I would need to disable/re enable this device in device manager to make it work again.

I installed the most updated drivers from the manufactures website, and for now that seems to have fixed the issue.

I also paired this up with the VANTEC UGT-IH203 2-Port USB 3.0 Front Panel, Item #: N82E16811999246 and it is working great as well.

5 out of 5 eggsWorks as advertised

Pros: USB3 external drive 7200rpm SATA II sustained transfer speeds of 130-140 MB's; the same as using a USB3 port on an Intel Z77 board. Internal 20 pin for front panel fits perfectly.

Cons: Mounting bracket just a hair short in my case, had to bend slightly to allow board to fit snugly into slot,

Other Thoughts: Purchased this board to overcome Intel's decision to turn off USB3 driver install on Z77 chipset when using consumer grade motherboards in a server operating system. Installed in a WHS 2011 and USB3 works perfectly off this card.
