Which storage device works faster than a common hard disk and has no moving parts?

Correct answer: Solid State Drive

The governing concept is the difference between solid-state and mechanical storage. A solid-state drive, or SSD, stores data in flash memory and has no spinning platters or moving read head. It therefore usually provides faster access and quieter operation than a conventional hard disk, making option C correct. CDs, magnetic tape, and floppy disks use slower removable or magnetic media and do not provide this combination.
