Data storage refers to magnetic, optical or mechanical media that records and preserves digital information for ongoing or future operations.

What is data storage? Data storage is the retention of information via technology that is explicitly designed to store that data and make it as accessible as possible.

Data storage, a cornerstone of computing, pertains to preserving digital information in a medium for subsequent retrieval. From its inception, this information has been stored as binary data, represented by a sequence of ones and zeros. Over the years, the mediums to house this data have evolved significantly, increasing in speed and volume.

Data storage essentially means that files and documents are recorded digitally and saved in a storage system for future use. Storage systems may rely on electromagnetic, optical or other media to preserve and restore the data if needed.
