Which statement about solid-state media is true?

Which statement about solid-state media is true?

• A. No moving parts, robust, but finite read/write cycles
• B. Uses magnetic spinning disks to store data
• C. Has unlimited write cycles and is always cheap
• D. Requires constant power to retain data

Answer: (C)

Solid-state media store data in flash memory with no moving parts, which makes them robust and reliable since there are no spinning platters or read/write heads that can fail from shocks or vibration. However, the flash cells have a finite number of write/erase cycles, so each cell wears out over time and performance can degrade unless wear leveling is used to extend lifespan. They retain data without power, so constant power isn’t required to keep information. They aren’t magnetic spinning disks, and while prices have been dropping, they aren’t universally cheap compared with all other storage options. So the true description is that solid-state media have no moving parts, are robust, but have finite read/write cycles.
