Bought was the card to store and play music, so no great demands in terms of speed or stress. Nevertheless, of course, the AS SSD benchmark was chased over it, with ordinary results Read / Write, Sequential: 17,76 / 11,55 MB / s, access times 0.918 / 3.223 ms. And the Crystal Disk Mark also not so bad for a Class 6 card, with 18,59 / 12,23 MB / S Sequential (Class 10: 21.81 / 12.54) or 4K QD32 with 5.014 / 0.653 ( Class 10: 5,537 / 0,710).
In this respect - who already has tens ... adapter and simply requires only one card is well served by the Samsung MicroSDHD and can do no wrong.
Of course - when it comes to HD photos, and at the same fast continuous shooting, it should be a faster card, but for normal use in the phone, the music playing, or simply as a memory, it is a good workhorse.
If back is necessary, I take pleasure again on this card of the brand manufacturer back!
