Summary
The main trends observed by comparing solid-state technology and magnetic or optical storage technologies are about the same:
Miniaturization and increasing storage density
Continuous price erosion
Expansion into the new and nontraditional markets
Solid-state technology is, for example, attempting to capture some market share from the magnetic storage devices by entering the HDD market with solid-state drives. At the same time, HDD technology has started competing with Flash technology in the field of hand-held devices with products like IBM Microdrive. It seems at the moment that the cost of storage will determine the future outcome of this battle.
