Originally posted by Rory Why not go with one 32 and be done with it instead of 2 16s? If you're travelling, and have two cards, that's that much more chance of losing one.
That could also be interpreted the other way. I would rather have multiple cards rather than one big card in case a card got damaged, corrupted, lost, or stolen. That way only a fraction of photos are lost instead of all. I have about 5 4GB cards, I bought 3 in a special pricing when i got my dslr. I bought the second on another sale before I went on a vacation. I dont shoot a lot either, but managed to fill 4 cards on that vacation.
My advice: buy multiple, but big enough for your shooting style. And of course take advantage of sales or rebate offers.
