Conclusion:
The stick remains far short of the advertised back "up to 130MB / s." Still, I can not blame the stick total letdown because same-priced sticks also USB3 ausreizen far nciht.
If you want more speed, already need to invest about 20% more. The fastest USB stick, which I could measure up to now is the Transcend JetFlash 780, achieved the real 130 MB / s.
