3.5-inch drive

A 3.5-inch drive refers to a type of data storage device, primarily a floppy disk drive or hard disk drive, that measures 3.5 inches across. This size was commonly used for floppy disks in the late 20th century, allowing users to store and transfer files between computers. In hard drives, the term indicates a standard size for internal storage in desktops. Though largely replaced by USB drives and cloud storage, 3.5-inch drives were once a vital part of personal computing, enabling data backup and software distribution in an era before more modern technologies.
