THE MICRODUO 3.0 64GB
Just like its predecessor the microDuo 3.0 model features the same tiny housing (27.63mm in length, 16.46mm in width and 8.56mm thick) but instead of a brown cap it comes with a black one.
If you're wondering about the size of the microDuo 3.0 line you can check the above picture which has several other drives (the microDuo 3.0 is 3rd from the top).
At the front/top of the drive Kingston has placed their logo (on the plastic cap), the model name and capacity.
The black cap is used to keep the micro USB connector protected at all times (the company name is also present at the bottom of the cap as you can see above).
