The box included a molex to SATA adapter (which I needed)
The box also contained two different kind of bay ports - helpful
Getting the card situated in my Dell Studio XPS 9100 was easy (in the back, not front)
The manual that comes with it is a complete waste of time
The CD did not autorun and I could not locate the proper file on it to run
AND you CAN get around this by going to: (I posted the link, but Amazon stripped it: go to the startech website and click on support, click on product manuals and driver downloads,
then plug in the model name: pexusb3s2 you'll see three files download the manual and the driver.)
I downloaded both the manual which is better than the one in the box and the driver which is more expedient and is updated.
So - I was able to install it and it is working fine, though it required patience. I'm glad I have a bit of a background in this. If you've never installed a
card before, you might feel totally lost.
As for the seller: the product arrived with the speed of lightning (well, almost) and in good shape
With the exception of the instruction manual not specifying exactly which folder on the CD contained the "setup.exe" file for this product I have no complaints with the installation or performance of this USB 3.0 card adapter. The file is located at
\PCIe\NEC uPD720200\setup.exe on the CD and is the same version as the one on their website.
The file transfer speed from my internal hard drive to the external 3TB Western Digital drive (purchased at Costco on sale for $109.99) was about 105 Megabytes/sec - much faster than the same drive plugged into the motherboard's USB 2.0 port. The USB 3.0 port speed matched that of transfering files between two internal SATA drives.
Because all of my computer's SATA power supply connectors were being used (three internal hard drives and two Blu-Ray drives) I had to buy a six dollar SATA power supply "Y" (splitter) cable assembly to connect with the supplied power cable of the USB 3.0 card adapter but if you have a spare SATA power connector in your computer you will not have to buy anything beyond what comes in the box.
Once you install the driver the Windows 7 device manager should show "Renesas Electronics USB 3.0 Host Controller" and "Renesas Electronics USB 3.0 Root Hub" under the "Universal Serial Bus controllers" section.
I highly recommend this product!
UPDATE: December 2, 2011
So far no problems with this product. I did want to add that the data transfer rate will depend on if you are transferring one huge file (as in my test results mentioned above) or transferring hundreds of little files.Read more ›
For $30 I decided to take the risk and see if I could get this to work in my 2006 Mac Pro. Had to do some digging on the net to find some hacked drivers but they are out there. Using a Seagate GoFlex 3TB USB 3 drive I'm getting 96 MB/s write and 115 MB/s read speeds.
Also, due to poor information from the manufacturer's customer service area, I wasted a few dollars buying a Sata to LP4 Pin Power adapter that was not needed. Prior to purchasing this unit, I contatce the the manufacturer's customer service area to ask about comatability with my computer, etc. During that conversation, I was told that the unit did not come with the Sata to LP4 adapter I would need, even though the description said one was included in the package. Thus, I bought a separate adapter along with this unit. When both were received in the same shipping carton, the package for this unit did, in fact, contain an equivalent functioning adapter with 6" connectors.
This card is a great way to upgrade to USB 3.0.

Works perfectly, and for a cheap price. The only reason for four stars is that it would be nice to have more ports as USB 3.0 peripherals often don't have pass through.Published on May 27, 2014 by Amazon Customer
