Solid-state storage (SSS) is non-volatile computer storage that has no moving parts; it uses only electronic circuits. This solid-state design differs from the commonly used competing technology of electromechanical magnetic storage which uses moving media coated with magnetic material.Generally, SSS is much faster but more expensive per unit of storage.
SSS devices typically use flash memory, but some use battery-backed random-access memory (RAM). Devices come in various types, form factors, storage sizes, and interfacing options to satisfy application requirements for many computer systems and appliances.
