One thing I\'ve never understood is why does a card of higher denomination (say 128GB) have a higher burst rate than a smaller card (say 64GB) even though the cards are the same specification and speed?
Example from Lars data:
I don\'t understand how the capacity of the card can make such a difference in thru put. Certainly neither card approaches full on the test.
Anyone have insight on this?

The difference you pointed out is very big. I\'m also surprised by that. But you could actually talk about good and bad copies of the cards , just like lenses here. Those cards that I have many copies of will also give me a little bit different result depending on what copy I used.
Most times the larger card will be a little bit faster than the smaller card when shooting with the same kind of cards.
With these two cards and such a large difference. I belive some of it is has to do with the fact that the 32GB card is a older card, than the 64GB card. Many brands make some changes in their cards when producing it for a couple of years. See how different the Sandisk Extreme Pro cards are today, compared to when they first where released.
