Guaranteed bandwidth for each port 07/23/2010
The chip this card is based on has a completely separate USB controller for each port, and as such can deliver the full 480Mbit for each port, for a total of 1920Mbit. Normal USB cards only have one actual controller, plus a built-in hub to share the bandwidth between all the ports, for 480Mbit total.
That means that if you attach a hard drive to each port, you'll get full USB 2.0 performance out of each drive *simultaneously*.
Since it shows up as *8* PCIe devices I suspect Windows will have a bit of cow with drivers...
I don't own this card yet, but I'll be ordering one very shortly. I just wanted to put this information here because I've looked for a card like this for quite a while, and just happened to run across info on this chip by accident.
