Thank you, Pete.
I have read some more on the forum about the Firestore, and it seems like I should go with the P2 cards.
But then, how do I get the cards onto my computer?
I will be shooting away from home, and my Mac has to stay behind.
I saw a few P2 card drives on the net. Do these act as hard drives that download and then wipe your card, and then would connect to my Mac at the end of the day?
