If time is of the essence, the P2 Store can verify and format your cards, so you can transfer the data and clean the cards at a faster rate. You can dump to the P2 Store and format the card before the card recording in the camera is full so you can swap and shoot pretty much continuosly. I don't think you can do it that fast on a mac and only the PC software allows you to format the card in the computer.
