Under a trnd product tests, I test the Evo Samsung MicroSDHC 32GB. On receipt of the packet I have the memory card inserted into the phone, and photos and videos copied to the card. Then I put the card with the included USB adapter in my PC and copy the data very quickly on the PC. Chill does it much faster than with my old memory card. The USB adapter I can plug in my laptop and TV and can play the videos without stuttering. The card is for me so fast enough. Toll I think the 5-protect the memory card, which certainly is the protection against vibration and extreme temperatures most important. Because I can not imagine that I drop into the water my memory card to me - after all, she's in the phone or tablet - and I would never throw them into the water. Fall down can happen and that one takes the cell phone in the winter or summer outdoors in cold and heat, is much more likely. And by x-ray my cards were also never damaged. To test the robustness, but then I have put the memory card in a glass of water and after she had survived that, even for an hour in the freezer of the refrigerator. Everything has it survived without complaint - the data were unreadable even without problems.
