in my Nikon too slow ..

The advantage of this SD card is the design, the speed and promise in the price. In my Nikons though they are as good as useless. Slow slowly save picture by picture. In a less than half as fast SD card from Sandisk (acc. To label) is the whole beisspielsweise so fast that you do not even notice the save. The same problem I have, incidentally, when the CF cards of this company. Also, since you get the feeling that after the third imager everything to a halt and even at Jpeg s and not on RAW files. Since then first circuit when the memory is full of Nikon.
I take them now for my tablet, because they are definitely useless to take pictures.

Conclusion: Either the parts have a problem with Nikon or four times I had bad luck with CF and SD cards of this company. The label and the practice speak with me in any case an entirely different language. When you see the many positive reviews, then they must be good for something, yes. Do they hinder the work considerably and it was the last time that I tried it with Transcend.
