There are mainly 2 types of drives: HDD (hard disk drive) and SSD (solid-state drive). HDDs are installed in most PCs and laptops. They contain moving parts as such, they are prone to heating issues and can be damaged. All reading and writing operations are performed due to rotation of the plates and the sensing head located at a few nanometers. Solid-state drives do not contain any moving parts and thus, run cooler and use less energy. Besides, they deliver superior performance and durability.
