Storage devices are essential tools that allow data to be stored and retrieved. These tools are also commonly referred to as data storage devices or simply storage mediums. Synonyms for storage devices include storage media, data carriers, data storage equipment, backup devices, and memory devices. Storage media commonly refers to materials or devices on which data can be stored, such as CDs and DVDs. Data carriers, on the other hand, refers to any physical medium that can hold data, from USB flash drives to external hard drives. Backup devices serve as a means of protecting data by providing a safety copy, while memory devices enable computers and other computing devices to access stored data.
