For MP3 in the car, it is sufficient. A small LED's does not interfere too. As a test I wanted to install Win7. With Oracle VM Virtual Box How do I choose the stick as a storage location. Work slowly and dignified, which is not completed remains lie. Remained lying is nothing :) Other USB sticks are felt doubly fast. From installation hear nothing. As with SSD :) Now formatted again and lined with MP3. Invisible it does its work in the car.
