USB3 card

L

Hi

I want to install a USB3 card to my desktop PC. I have a free PCI slot,
but understand that won't allow the full speed increase of USB3.

I also have an AGI Express slot (purple) on my ASRock motherboard - can
that be used with a PCIE USB3 card?

Many thanks

See the "PCI-based AGP ports" section of this article.

http://en.wikipedia.org/wiki/Agp

AGP protocol, consists of two parts. Random access via a PCI
protocol, plus a burst transfer protocol specific to AGP.
On non AGP slots (AGI, AGX, and friends), those would
be non-genuine AGP solutions.

If all you have is basically PCI in the computer,
then you're limited to PCI performance (~110MB/sec practical
transfer rate, approximately speaking).

And they actually make one that goes from PCI to USB3.

You see, on the Koutech card, there is a PCI to PCI Express x1
bridge chip on the back of the card.

And a USB3 chip on the front (square chip next to the four caps).

This is a second Koutech-made card, with the bridge on the back.

Using a bridge chip, makes the cards cost more.

Startech appears to make one as well. But Startech absolutely
refuses to show a picture of the back of the card, where the
bridge is located.

Whereas most cards, go from PCI Express x1 to USB3, a different
bus standard. Notice the smaller connector - it doesn't fit PCI.
