Hard Disk Drive
People still use traditional hard disk drives as storage units. A hard disk drive is a mechanical device which writes data to a spinning disk with magnetic field. Raising of the need of more speed, more performance and more storage capacity brought problems together. HDDs don't support the needs of today's people.
Solid State Drive
A solid state drive is not a mechanical device as hard disks. There is no spinning piece. They resist high vibrations and impacts. You can move a SSD in runtime.
Solid state disks write the data to cells electrically. The SSDs run with about 1ms random access time and this gives more speed to the user.
