That is why these cameras have buffer.

Class 10 only means that card is capable of a minimum 10mb/sec writing speed. But each manufacturer might be rating their cards on top of this CLASS rating.

I have tried it. Same results.
BTW, one of the posters here has 90mb/sec CF and 95mb/sec SD with the same exact problem.
So it is obvious to me that there is some kind of the bug. My camera is one of the first ones and it was purchased in April of last year.
