I need a new USB because my old one was too slow and was only 2GB.
The USB also needs to have a good-looking design because I want to show my friends.
Sigh. If appearance is that important, base your purchasing decision on it. For the rest of us, a USB flash drive is a tool. As far as speed is concerned, you will not notice any speed difference in any of the modern USB 2.0 flash drives.
