Difference between SSD and HDD Storage Capacity

The above figure shows that the internal architecture of a hard disk is made of several platters, and platters hold the information; the functions of the heads are to read or write information from the disk surface. The surface of the platter is made of several tracks, and each track is divided into sectors as shown in the below figure.
