A spinning metal platter that remembers everything so your brain doesn't have to.
means A data storage device that uses rigid, rapidly spinning magnetic platters to permanently store and retrieve digital information.

IBM introduced the technology in the 1950s, but the 'hard disk' name became common once floppy disks arrived in the 1970s and needed something to contrast against.
