What is Amoeba modular USB flash ?

Amoeba modular USB flash, envisioned by designer Hyunsoo Song from SADI , is a brand new design/concept which seems to inspire next generation USB drives.
If you've ever carried multiple thumb drives, one for office and other for personal stuff, then this is the next one that you should purchase.
Amoeba modular USB flash is divided into four sectors which are physically separable from each other. Each sector can store data individually and can be used independently or collectively. The image will help your understand what it is like.

I hope you are impressed.
