We have seen quite a few USB thumb drives recently, they come in different shapes and sizes. Talking about size…the flash drive shown above may as well qualify to be the smallest USB flash drive in the world. Comes primarily in 8 GB capacity, the Buffalo RUF2-P Thumbkey is available in 3 different colors.

The device when attached to the PC/Laptop, is just 5mm off, so it can remain attached to the computer.
