For my purposes, the map extends this model, I have the faster from the cell phone out and for pure - because no one notices the difference.
in general: the difference of brand memory cards (whether SanDisk or Transcend) compared to various "NoName" is considerable. NoName cards allegedly 30-60MB / s in read mode provide nowhere near the levels of brand cards. Therefore, I strongly urge the "NoName" cards. The same also in USB sticks!
