The map is very high and makes no problems. a speed test I did not do, but that's not necessary in my opinion, because K-5 the full 7 frames / second in Raw (approximately 22MB per image) easily achieved with the Pentax and also at Full HD Recording at 30fps NOT stuttering or other problems were.
So Consistently positivist. Alerdings there was even a small problem:
I was taking pictures on the camera and showed suddenly that no images on the card are. More images could not be saved. After switching off and on again ("Have you tried to turn it off and on again?" :) However, there were up to the last all back all pictures. But has been a one-time mistake and whether camera or card were to blame, I can not say.

Very inexpensive recommendation!
