I have a desired set-up in mind, but not positive my D7k can be setup like I want it? It will be a month before I will find out if it works (unless anyone has experience with it), because I will be getting the Patriot LX series 64gb SDXC in about a month (after its certification on the D7k).

My intention is to use my 32gb SDHC class 10 in slot #1 and a 64gb SDXC class 10 in slot #2. I am shooting in raw only, and HD video, so I would like Slot #1 set-up for Raw only and Slot #2 set-up for backup and videos.

I hope it can be set-up this way, but not sure?
