what size and speed memory cards for weddings?

i recently lost all my cards and need to get new ones... sucks
i shoot 1dmk3 and 30d now would like upgrade the 30 to a 5d2.
these would be used for weddings. well this would be the most demanding thing they would be used for lol.
1. what speed?
2. what size? i know there are a couple theories on this. just looking to see what the masses say. large so you dont have to change as often and possibly miss something, or more smaller cards to reduce the loss if something happens to a card.
3. what brand ?

You don't need anything specifically for weddings. Whatever you would normally use is fine. Don't use such a big card that if it crashes you lose everything, but don't use such a small card that you have to change it every hour.

I use 16GB cards, and rarely have to change cards. When I do they go into a GEPE Cardsafe. 8GB I have to change too often, and 32GB are too expensive.

I trust two brands:
- Transcend 300X 16GB. These are high quality cards with SLC memory cells and error checking and correction. Other speeds are lower quality.
- Sandisk 16GB. I've not had a Sandisk card fail yet, even though they're MLC they're high quality. Choose whichever model/speed you like.

i shoot raw and like the 16g and 32 g sandisk iv's

16GB Sandisk Extreme x 5
8GB Sandisk Extreme IV x 2

The only reason to have large fast cards is if you will be shooting video.

Is that a universal rule or something?

I have 10 of these and they are what I mainly use. I have few other miscellaneous Sandisk/Lexar cards but only use them if all the Transcend cards get filled. Which rarely happens.

We use the Lexar 16GB professional 400x cards and sandisk 8gb 60mb's cards.

I tried this Lexar this year and have used them all season with zero issues. Very pleasently surprised. We carry 3 cameras so its nice putting in the 16GB cards and shooting all day w/o changing cards---I think its about 1100 shots on the Mark3,,maybe more.

You stand a far better chance of loosing a card V/S a card failure so thats why we use the 16GB cards. Ive never had a card failure ever (knock on wood) and the pros at sandisc told me 99% of card failures are due to pilot error......improper formatting, sticking them in your pocket and getting them contaminated and most of all moisture contamination. Theres a reason they come with those plastic cases. I format everytime it goes in the camera, and the only time its out of its plastic case is to install it in the camera.

exactly... less fumbling with cards the less user error
however the only card i have ever had fail was a lexar and it was 5+ years ago and they were able to recover the images

I use three cameras and have an 8 gig card in each of them. One camera has a 24-70, another with a 70-200 and the third is the camera I'll change lenses on. This also keeps the sensors cleaner from not changing lenses throughout the day.
I've never run out of space so, never have to change cards.

I have one camera dedicated to the 24-70 with a 16GB card in it, a 12MP cameras. I sometimes have to change cards on that one, but not every wedding.

I use 8GB SanDisk Extremes. I get ~250 photos per card in my 5D MKII's.
