Answer :
The answer is : Solid state drives, Hybrid hard drives and magnetic hard drives. The 3 types of technologies that are used inside hard drives are Solid state drives, Hybrid hard drives and magnetic hard drives.
A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit (ic) assemblies as memory to store data purposely. A hybrid drive, or SSHD, is a physical storage device that combines a fast storage medium such solid-state drive (SSD) with a hard disk drive (HDD), with the intention of adding some of the speed of flash storage to the cost-effective storage capacity of traditional HDDs. A Magnetic hard drive is a data storage device that uses magnetic storage to store and retrieve digital information using one or more rapidly rotating disks (platters) coated with magnetic material.
