Solid state storage regards media and devices that are not moving as in conventional hard disks. Solid states devices include SSDs and flash memory modules.

Solid state backing storage, or backup storage, is a way of storing information that has no moving parts. The small, plug-in modules often called USB drives or thumb drives are a common example of this type of storage.
The two names of backing storage are secondary storage and auxiliary storage. Secondary storage refers to non-volatile storage that holds data and programs not currently in use by the computer's main memory, while auxiliary storage encompasses a wider range of devices, including hard drives, solid-state drives, and optical discs. Both types are essential for long-term data retention and retrieval.

Optical backing storage refers to data storage technology that uses optical discs, such as CDs, DVDs, and Blu-ray discs, to store and retrieve digital information. These discs are read and written using laser technology, allowing for high-capacity storage and durability. Optical backing storage is often used for archival purposes, software distribution, and media storage due to its resistance to electromagnetic interference and long shelf life. However, it is generally slower than other storage methods like hard drives or solid-state drives.
Solid state drives, or SSD, are storage devices that uses integrated circuit assemblies as memory. Flash drives, compact flash, and MultiMedia cards are examples of solid state storage devices.

The overall trend in secondary storage device is the migration from rotating magnetic discs to solid state storage. Solid state drives (SSD's) are however considerably more costly than older types of storage.
Backing storage refers to non-volatile storage systems used to retain data permanently, such as hard drives, solid-state drives, and optical discs. It serves as a complement to primary storage (like RAM) by providing a larger capacity for data retention, even when the power is off. A media track, on the other hand, is a concentric circle on a storage medium, such as a hard disk or optical disc, where data is recorded and retrieved. Each track can hold a significant amount of information organized into sectors, which are the smallest units of storage on the medium.
