Top critical review
Good speed, easy to install, however watch out with problems booting form it. :-(

The device did what I needed it gave me a speed boost when using my Zalman ODD.
It works fine and give me better throughput that USB 2.0, not as fast as I expected given the USB 3.0 spec but that could be my old 2.5HDD in the Zalman. I will try with an SSD next time to try and stress the card.
The only real downside I had is that I am unable to boot from it. It is like the bios doesnt initialialize the card until later on in the boot process. This is a real pain because it means I couldn't use the Zalman in either USB 2.0 or USB 3.0 modes, there was no power until the OS started to boot. I will grant another star if I can get around this or prove to myself it is a problem with my Motherboard.
In summary, if you are short of USB ports, or if you only have USB 2.0 and have some USB 3.0 compatible devices that are being bottlenecked then this will be a decent buy. I don't think it will max out an high speed SSD.. but you will probably get near the max throughput of most mechanical external drives.
