In continuous shooting, all cameras I used shoot for a few seconds, then stop. For example, a Nikon D7000 with a 200x (30 MB/s) single SD card makes ten RAW photos (approx. 19 MB each), six shots per second, then stops for a few seconds when the buffer is full.
Obviously, the SD card is too slow. But is the SD card the only bottleneck, or does it stop shooting also because the camera cannot process more images?
In other words, if I buy a 600x (90 MB/s) SD card or an even faster one, how this will influence the number of shoots per burst?
