Express Card uses PCIe. That is the point of PCIe.

Architecture section of the MacBook Pro developer documents says: "1-lane PCI Express link and one USB 2.0 interface for the ExpressCard/34 slot"

The PCI-e is connected with both USB and PCI-E x1. The USB is for stuff like modems and stuff, and the PCI-E is for other stuff like eSATA, etc.

my FW800 card (Sonnet) is a lot faster for HDs than FW800 so I wouldn't worry about it being a USB connection given a good card.
