Despite currently available Solid State Drives being smaller, more efficient and faster than standard, spinning hard drives, researchers in Japan are working on making them much smaller and even more energy efficient. Keio University in Tokyo and Toshiba have teamed up to produce a prototype SSD that is the size of a postage stamp but which has a 1TB capacity. The team, headed up by Professor Tadahiro Kuroda at the University, claims to have discovered a technology that can reduce the size of current SSDs by 90 percent while making them 70 percent more efficient.
