This is has probably been discussed quite a bit over the years, but technology is changing, so the answers probably are as well.
Basically, I am curious "how large is too large" in terms of GB for memory cards. Some people mention that having one huge card is like putting all of your eggs in one basket- that is, if it breaks/fails, gets lost, etc ALL of those pics are lost with it. So some people prefer to shoot several medium-sized cards (medium sized just meaning smaller than whatever would be considered huge, relative to what is available at this point in time).
The only type of card I currently use is Compact Flash, and the largest I own is a 32GB (I have a few 16GB also). I am thinking about buying some more cards for my Yellowstone trip. I am wondering a few things:
Should I go bigger than 32GB? I'm looking at a search result on a website and see up to 256GB. I found this cool calculator http://memorycardcalculator.com/ which gives you rough estimates of how many pics you can fit on a certain size card based on file type, MP, etc. For my 7D mk II body I could fit 4000+ pics on a 256GB card...seems too much to put in one spot IMO. I could see maybe going to 64GB. Opinions?
My 7D mkII also has dual card slots (one CF and one SD) and I was thinking of buying some SD cards to go along with my current CF cards - as I shoot, I can have every photo recorded to both cards simultaneously so I have a backup of all pics in case one card fails.
I also have no idea how many pics I will shoot per day on any trip, but I'd rather have more space than I need, than less.
Any advice would be appreciated, especially from someone that has experience with longer shoots and medium to large cards, etc. Thanks
