I began to research further unhappy about the situation and found these SD cards. Somewhat surprised by the price but hopefully I ordered the card here on Amazon. What can I say? After several shots among other things a 14 hours day of shooting - not a single dropout. The map seems to be fast enough for this. I do not have software that shows me the data rate and probably there will be no 45MB / s, but as long as I can make my shots as usual I'm happy and satisfied. Everyone has the same problem, you should consider purchasing here. Probably have the SD card manufacturers only now understood, as before so mainly CompactFlash cards can be used in other DSLR cameras.
Conclusion: Who is looking is for a quick SD card, will not pass the SanDisk Extreme Pro. Enjoy the photos! :)
