WRITING: 60m / s
READING: 79m / s
there is nothing surprising as it seems that in most tests done on the TRANSCEND brand, speed is not the one given (but again the first time that I see a different playback speed for the reference on the map.
but in any case this copy, the write speed is even announced, and that's what matters most.
Conclusion:
you can use this speed to your machine is a good choice, but you just wary of performance given by the manufacturer (for all).
if that comment helped you thank you to note, if this is not the case thank you to a point to be able to respond.
