I have my D800 setup as the CF card being the primary and the SD as backup shooting in RAW loss less compressed.
My CF Card is a Transcend 32GB 400X which seems to be working pretty good.
My question is this :
Do I need a faster CF card ? If my SD slot is for backup then it should be a 32GB card as well, but how fast should this card be to be able to keep up with the CF card ? or how does the D800 work when it comes to writing the same file to two different kind of cards ?
