Two side memory disk
Have you ever in an embarrassing situation, when you show up your data form your USB drive but suddenly notice that there is some data which you want to keep in private? Or you always do not know where your USB drive is especially when you need it?
Now you can simply use this two-side memory disk with two different color to achieve the goal. One is for your personal usage and the other one is for business. With a key ring you can also hook on to your key to make it more practical.
