How about something really old?
Holographic storage technology. It has been around for many years, but various issues keep it from becoming mainstream.
Basically, it is the use of lazers in a crystaline medium to store data at the intersection of two or more lazers. It is basically limitless storage space, based on how well you can make the lazers. It is invulnerable to EMPs, so it has particular military uses. However, it is very sensitive to vibrations. They are also very big units (usually the size of a large desk). They are also bloody expensive.
Search for holographic storage on google, and you should get a lot of stuff there. Good luck.
