It does come with the PCI-E interface card. You get to choose what Interface card you want, either PCI-E or Express Card 34. We had one on demo for a week and I highly recommend it. we ordered 2, one for each edit bay and an extra Express card adapter for when we are on long road trips. It takes all pro level interface cards and reads them at Good speeds, much better than USB card readers.
