use the card now greater 6 months with a 30-oly e. when shooting sports, I can in JPEG mode kontinunierlich 5 frames / sec shoot without "standstill" by writing. RAW, the camera / sec to store 10 images at 5 pictures, then only 2 frames / sec. the always enough for each sporting event - so far with more than 10,000 images no problems.
Theoretically, the oly 14 images at 5 frames / sec continuously in RAW mode, so only 4 stars.
