There's no big choice when it comes to cards. I could not find SD cards fast as XQDs at writing speed. But these beasts are expensive, gosh! The SD cards have the advantage that there are tons of readers out for them. I have no clear opininon about that, the D810 also has mixed slots. And the D850 only wil be as fast as the slowest card...
