Every USB device uses a and Product ID (PID) to identify itself to your computer so it can load the right drivers.
Because the hardware is generic, performance can vary wildly between units. For instance, some users have reported that formatting these specific 32GB sticks with the file system can provide a noticeable increase in file transfer bandwidth compared to the standard FAT32 format. USB 3.0 Flash Drive Speed Tests - VID = 346d, PID = 5678
