Solid-state drives actually aren't hard drives in the traditional sense of the term, as there are no moving parts involved. A traditional hard disk drive (HDD) consists of a spinning disk with a read/write head on a mechanical arm. An SSD, on the other hand, has anarray of semiconductor memory organized as a disk drive, using integrated circuits (ICs) rather than magnetic or optical storage media.
Development and adoption of SSDs has been driven by a rapidly expanding need for higher input/output (I/O) performance. SSDs have much lower random access and read access latency than HDDs, making them ideal for both heavy read and random workloads. That lower latency is the direct result of the ability of flash SSD to read data directly and immediately from a specific flash SSD cell location. High-performanceservers, laptops, desktops or any application that needs to deliver information in real-time or near real-time can benefit from solid-state drive technology.
