Which storage type has no moving parts?

• A. SSD
• B. HDD
• C. Optical
• D. Tape

Answer: (A)

Storage devices that have no moving parts rely on solid-state memory. They store data in flash memory cells, so there are no spinning disks or moving read/write heads. This absence of mechanical components means faster, more reliable access to data and less power usage. Among common storage types, the one that fits this description is the solid-state drive.

Hard disk drives use spinning magnetic disks with moving heads, Optical discs use a laser on a rotating disc, and magnetic tape stores data on moving tape. All of these involve mechanical motion, unlike solid-state drives.
