Storage devices are essential components of computers and other digital systems that allow for the storage and retrieval of data. They come in various forms and technologies, each with its own characteristics, capacities, and performance levels. Storage devices are responsible for holding and preserving both the operating system and user data, such as documents, media files, applications, and more.

The primary function of storage devices is to store data in a non-volatile manner, meaning the data remains intact even when power is turned off. They enable the long-term retention of information and facilitate quick access to data whenever needed. Different storage devices cater to various requirements in terms of capacity, speed, portability, and cost-effectiveness.
