What will replace today's hard drives and flash memory devices? The former tend to be slow, the latter unsuited to long-term use. Then there is RAM, many forms of which are volatile--turn off the power, lose your data. These shortcomings, as well as the same demands that drive most technological innovation--to make it smaller, faster, cheaper, less prone to failure--have produced a number of candidate data-storage technologies in recent years, all of which offer some combination of advantages over the devices in wide use today.
