After I bought a 64GB SD card SaveTec and therefore was very happy, I have once this MicroSD ordered for my Tablet. Unfortunately, the speed is significantly worse than the "large" Model. It is about 2x slower and does not even reach the Class10 standard, with which it is advertised. (H2test shows only 8.45 MB / s write, the same SDCardSlot reached the other card via 20MB / s) The reading quality is similarly disappointing. A good price / performance ratio, but too slowly.
