Price / performance ratio but a little slow

So far I have two of the red / gray SanDisk 64GB memory card (SDSDQUAN-064G-G4A Ultra 64GB Android) and have this time opted for this more favorable.
Unfortunately the Gschwindigkeitsnachteil is noticeable when transferring images and continuous shooting.
Unfortunately, the microSD card is slower than the "normal" 64GB SD Sandisk, both of which are indicated with 30MB / s read.

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!
