Solid-state storage

• Solid-state storage is a nonvolatile, removable storage medium that employs integrated circuits (ICs) rather than magnetic or optical media. It is the equivalent of large-capacity, nonvolatile memory. 
•  Solid-state storage media lags behind electromechanical drives in terms of storage capacity. As of this writing, flash memory USB devices can store up to approximately 1 gigabyte (GB), whereas hard drives commonly hold 100 GB or more.
