I bought this USB flash drive with a USB 3.0 card.
Installation and formatting folded problem-free.
The first copy, but then came the disillusionment; The write rate averaged 13-14 MB / s. With a USB 2.0 flash drive that would have been okay, but for USB 3.0 which is totally insufficient (in my opinion).
I first thought the problem would be my USB controller. After repeated Reinstalling Drivers and a test on my laptop became clear more and more that the stick of the stick was the bottleneck. At the file system, it was not. I've tried both NTFS and exFAT.
The reading rate was decent 70-100 MB / s. This is USB 3.0!
Property me now ordered a more expensive drive for 24. Let's see if this also disappointed me.
2/5 stars.
Edit: I would like to say that there is 2.0 (!!!) Sticks are USB, which have an almost twice as high write rate.
