Solid state drives, as the name suggests, don’t have any moving parts, unlike hard disk drives. Instead, data is stored on a series of NAND chips, which can retain their charge without a power source. Hard disk drives (HDDs) store data on a series of spinning magnetic disks called platters.

What does a class diagram do?

Class diagrams are the blueprints of your system or subsystem. You can use class diagrams to model the objects that make up the system, to display the relationships between the objects, and to describe what those objects do and the services that they provide.
