I have previously had another CF card with Kingston 45MB / s, so I can definitely recommend and is a must especially in sequential shots 8 frames per second, as Kingston has made limp and Camera blocked for 10 to 12 images to make empty to the memory. With the Sandisk is now no longer I can now 25 and making more photos without the shutter button is blöckiert to empty the camera's memory.
A must in Semipofessionellen area. (I have a Nikon D300)
