Not so fast, as advertised

Shortly beforehand, the map has been tested with an internal PC Card Reader (built in 2014), both with CrystalMark3D, as well as check Flash. Application is a Samsung S5mini.
It should be a quick card to EVT. To change from smartphone in a cam.
After reading some tests and the previous reviews here, we chose the 32GB variant.
At Amazon, as usual, easy ordering, fast, direct shipping, good packaging, on 22/12. ordered, on 24.12. mornings there. Perfect !!
Immediately after unpacking pushed into the card reader and run the Read / Write test.
From the measurements that do not reach the advertised speeds, I have to compare my 64GB SanDisk Extreme SDXC (Class 10 UHS I), which is currently in the cam, tested. This achieved in designated with both programs significantly higher values ​​in the Write / Read range.
Even if I do not really need the velocities in the smartphone, just to insert the card in other ways, I have opted for this.
I therefore can not confirm the partially reached speeds (above the manufacturer's instructions) other users!
To verify the results I've tested the card even in internal laptop Reader (built in 2014), still can not, preceding the tests, different results.
The read values ​​are to 30MB / s, Write the values ​​have not more than 25MB / s managed (according to the mentioned programs).
