With USB 3.0 which has nothing to do.

I am sorry to have to connect the people who complain about a speed problem with this stick.
Writing for an extended period of relatively large files is done with max. 20MB / s. I have not tested reading.
My 1 + 2 Tb disks write Alike loosely with 4-5 times the speed.
Structurally is against the stick nothing to say, is pretty small. It is not too hot even after prolonged use.
For me, an additional drawback: My Wiko Darkside does not recognize the 64 Gb drive. I'll return him anyway not because it is nice and small and also slightly more expensive than the same stick in USB 2.0 version.
