Thanks for the response! Don't think of this as questioning your answer, but do you mind providing the source of your information? Its not that I don't believe you, just I want to see what else I can learn.
Thanks WR2 for the information! If I understand correctly a 1x PCI express lane gives me about 250 mb/s of bandwidth.
The reason this is important is because I want to add either a eSATA card or USB 3.0 card for a external hard drive.
Does anyone have any recommendation which way i should go? From what I've heard is that real world results show esata as faster but usb 3.0 having more potential. Is 250 mb/s below the maximum for both?

Since the PCI Express port is wholly internal (no way to run a jack to the exterior) it's not suitable for the purposes you mention.
You'll need to find a USB3 or eSata Express Card to meet that requirement. Or just stick with your current USB2 ports for your external storage.
