Function:
The memory card is properly recognized by my digital camera. Saving takes place quite quickly (camera has 10 megapixels). Class 10 ranges for most applications, even in my camcorder (HD format, not full HD) could allow the videos to be stored smoothly. Therefore, I can not complain, a separate speed test I did not make myself.
Also on the PC with the adapter can be written without problems, the map, even after card reader while varying the speed. So many times I have to yes the card is not secure, so is the rate of 10 to 15 MB / s in order (indicating the operating system when copying).
Conclusion:
The memory card does what it should, and yet reliable. Therefore, I forgive the full five stars. If speed burglaries occur or errors I'll adjust my review accordingly.
