Primary storage devices are internal to the system and are the fastest of the memory/storage device category. Settings. A secondary storage device is also known as an auxiliary storage device, backup storage device, tier 2 storage, or external storage. A primary storage device is a medium that holds memory for short periods of time while a computer is running. Primary Storage Devices: Primary storage, also known as main storage or memory, is the area in a computer in which data is stored for quick access by the computer's processor. Secondary storage is used as a cheaper alternative to internal hard drives, and differs from components like a computer's RAM memory by being a permanent storage medium. 2. Primary storage is the collective methods and technologies used to capture and retain digital information that is in active use and critical for an organization’s operations. In contrast, secondary storage is used for data that is less frequently accessed, or no longer accessed at all. But these differences are important because they affect how we interact with data, namely by what the two different storage types can do. Primary storage (also known as main memory) is the component of the computer that holds data, programs and instructions that are currently in use.
