a hard disk is a type of storage device where data is stored on a rotating disk. it is composed of multiple platters that spin at very high speeds, creating a magnetic field. a solid state drive (ssd) is a type of storage device that uses electronic memory to store data. it does not have any movable parts, making it faster and more reliable than a hard disk.
