Write speed too slow

- Tested on multiple computers and multiple formatting the write speed is on average less than 10 MB / s on USB 3.0 Port.
- That was true for large and small files. In addition, I have tested a test program and different block sizes.
- My reference Stick reached 8-10 times faster.
- I had ordered three of these sticks because of chip-testing. They are all equally bad.

Here, the manufacturer seems to have after the test of CHIP installed poorer hardware. I send back the sticks.
