Memory Infinite USB storage
The Memory Infinite concept lets you plug together flexible USB drivers:
Memory Infinite has a USB male connector at one end and a female connector at the other, providing an “add up” concept for USB finger discs. By connecting one Memory Infinite with another to add up the storage capacity, the user won't waste the old storage capacity when getting a larger one. The user can choose to combine or separate Memory Infinite, making the usage of USB finger discs more convenient. And when Memory Infinite connects to a computer using its male end, other USB devices still can connect to its female end without having to occupy another USB port on the computer.
