A computer Internal Hard Drive (HDD) is a non-volatile data storage device. Non-volatile refers to storage devices that maintain stored data when turned off.

All computers need a storage device, and HDDs are just one example of a type of storage device.

A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage.

It is also sometimes called a semiconductor storage device, a solid-state device or a solid-state disk, even though SSDs lack the physical spinning disks and movable read–write heads used in hard disk drives (HDDs) and floppy disks.
