Solid-state drive (SSD)

SSD drives use what is called “solid state” memory. An SSD, or solid-state drive, is a type of storage device used in computers. This non-volatile storage media stores persistent data on solid-state flash memory.

The flash memory inside an SSD means data is written, transferred, and erased electronically and silently — SSDs do not have the moving parts found inside mechanical hard-disk drives (HDDs).

SSDs are much faster than hard drives since they use integrated circuits. SSDs use a special type of memory circuitry called non-volatile RAM (NVRAM) to store data, so everything stays in place even when the computer is turned off.

SSDs are lighter in weight than HDDs, use less power, and have virtually no vibration - due to no moving parts. They can also survive an accidental drop better than an HDD.

While HDDs are traditional storage devices with spinning platters that read and write data, SSDs use newer technology that stores data on instantly accessible memory chips.

SSDs are often used on high-end machines or as secondary storage devices inside consumer PCs.
