I see Lexar has announced a compact flash card that they say is 1000X.
I've seen some discussion of this before, but can't seem to spot it now so I apologize for starting a new thread on what may be an old topic. But, would some of the technical people out there care to offer some enlightenment as to what if any advantage there could be to super high speed cards?
My understanding is that for shooting, you really only need a card fast enough to clear out the buffer of your camera before it becomes full. Beyond that, the only advantage to a fast card is that it can transfer data more quickly to your computer.
Is that correct? And, if so, on a 7D (for example) how fast would that card need to be to keep ahead of the frame rate of the camera. I've never had a problem with my 7D, but I do buy better cards, although not the most expensive.
Am I missing something? Is there any reason to buy a super high speed card if you don't really care how long it takes to download your images to your computer? How do you know what speed is adequate for your camera?
