1.2 petabytes (1,024 terabytes) of storage on a single tiny disk. Inventor Philip Michael Thomas claims to be packing this much via his non-contact optical spintronics approach to data storage. Thomas has succeeded in coaxing electrons to spin in the same direction as opposed to current data storage methods which are hapless in the face of electron flip. Controlling the spin allows for smaller, higher capacity devices with prototypes expected in two to three years and commercial products in five.
