Final answer:
The statement is false. RAID and optical discs such as CDs are both considered mass storage devices.
Step-by-step explanation:
The statement is false. RAID (Redundant Array of Independent Disks) and optical discs, like CDs, are indeed types of mass storage devices. RAID is a way to store the same data in different places on multiple hard disks to protect data in the case of a drive failure. CDs were introduced in the 1990s and replaced cassette tapes as popular data and audio storage devices. They use a laser beam to read data via variations in reflections from the disc's surface, similar to how some barcode scanners operate.
