Abstract
A redundant array of independent storage devices is disclosed herein. The redundant storage device includes one or more atomic resolution storage devices and a control system. The atomic resolution storage device is configured to communicate with the control system as a redundant array of independent storage devices. Each atomic resolution storage device is a non-volatile memory component including a plurality of electron emitters, a medium having medium partitions, and a plurality of micromovers wherein each micromover is independently operable to move a medium partition relative to one or more electron emitters for redundant reading and writing of data at the media.
