Pros: I liked the idea of six ports on the card but you can only turn 4 of them on theoretically.

Cons: I have a new ASUS M4A89GTD Pro/USB3 MB adn AMD 6 core running Windows 7 64 bit. The card driver installed but non of the ports would work no matter the configuration of the jumpers. Device manager showed it installed properly but multiple working drives would not be recognized on any of the ports supplied. I purchased a Masscool at a quarter of the price and it works flawlessly. There techsupport just told me the same thing that the instructions say. It would not work with the jumpers configured in any possition.

Overall Review: I cannot recommend this card to anyone with similar hardware setup.

I would like to both pair.
