After receiving one of the "bad" 800Es I have ordered another. Now I need to buy a fast compactflash card for it. I bought the camera from B&H with the package that includes a Sandisk 32 GB 400x card. I understand that for burst shooting with the D800/E one needs a fast card so I am considering the Lexar 32GB 1000x and 800x cards. The 1000x is about 160% the price of the 800x. My question is whether the 1000x actually writes or performs any faster/better than the 800x. So far I have not found any review comparing them. Rob Galbraith's article does not include the 800x. Can anyone offer any advice as to whether the additional cost of the 1000x is justified in real world experience/performance? I will appreciate any advice you are able to offer.
