Looks like the SSD's of today are numbered! IBM's new memory, called "Racetrack Memory", is thousands of times faster than flash (Talking nanoseconds, not milliseconds), even more indestructable than flash, uses next to nothing for power, negligable temperatures, cheaper, and may usher in 2TB Ipods
Just when flash-based solid state drives are becoming the norm, IBM has developed a new type of solid state memory, dubbed “Racetrack”, that pretty much makes flash memory look obsolete. The new technology uses spintronics, which uses the spin of electrons to encode data rather than the electrons’ charge. The bits of data are stored in the magnetic domain walls along the silicon nanowire, or racetrack, thus allowing for super fast data transfers. The method allows for more energy efficient, faster, larger, and cheaper solid state memory—all while maintaining the same amount of “space” of current drives. In fact, according to IBM, the new Racetrack memory is capable of reading and writing data in less than a nanosecond and could provide up to 100x more storage than currently available drives on the market.
