- Memory 512 GB, in fact 477 GB. 477*1024*1024*1024 = 512'174'850'048 bytes Bigger size. The speed is good, much faster than USB flash drives from 3 years ago.
- The speed is clearly less than stated. Tested on a Samsung S7+ tablet . But everything is complicated there - the speed depends on the voltage and the protocol used. In general, according to the UHS-I class, the speed can OFFICIALLY be in the range from 12.5 to 126 mb / s. Again, see Wikipedia. As I understand it, in tests it can give out 90, but in real life it would get very hot and quickly fail.
