Currently I sport 4 8GB Compact Flash cards; lasts most of a day if I'm on vacation. I shoot RAW only, so the file sizes aren't going to get any smaller. So my initial reasoning was because I did not want a card to die on me, I opted for a more smaller capacity cards oppose to one large card—so in my initial case, I went for 4 8GB cards instead of 2 16GB cards. However the last time I went on a trip, I also lost a card because I had too many to worry about. Good thing I found it later, but not without an initial worry. Problem is I also shoot burst, so I don't actually keep track of the number of frames I have left on the card. I have encountered on numerous occasions that I ran out of memory in between shots and have missed opportune moments for a shot. I have also never had a card actually die on me, at least no the cards I've purchased; so far I've only bought the top-end Sandisk Extreme cards. So what are people's thoughts on this? Have you ever had a card die on you? Is the hassle of using more cards worth it the lower capacity? I am visiting B&H next week to buy a lens or two, so I was thinking I could pick up a few memory cards as well if I needed it.
