The 2 connectors are protected with sliding covers.
The set is well finished and exudes quality.
Total length of the USB drive: only 3.5 cm!
Actual speeds measured write: 12.1 MB / s
Actual flow rates measured in reading: 19.3 MB / s
So I put 40 minutes to fill it with 30 GB of data.
Note that my USB controller is not very powerful and ancient, so you might get better performance than me!
