Which of the following devices contains no moving parts and stores data in a digital format?

A Solid-State Drive (SSD) stores data using flash memory, which is entirely electronic and contains no platters, read/write heads, or motors, thus having no moving parts. This allows for faster data access and greater durability compared to traditional mechanical drives.

A cartridge tape drive uses magnetic tape and has moving parts for reading and writing data, such as reels and read/write heads.

A floppy disk drive uses a spinning magnetic disk and has mechanical components like a motor and read/write heads.

A hard disk drive (HDD) stores data on spinning platters and uses read/write heads that move across the platters, making it a device with significant moving parts.
