Which statement about solid-state drives is true?

Which statement about solid-state drives is true?

• A. Slower than HDDs
• B. Typically more expensive per GB but faster and more reliable
• C. Have moving parts
• D. Typically cheaper per GB and slower

Answer: (B)

SSDs deliver speed and reliability because they rely on flash memory with no moving parts. Data is accessed electronically by a controller, so there’s no spinning disk or moving read/write heads. That eliminates mechanical delays and wear, making operations much faster and more reliable than hard disk drives. The trade-off is cost per gigabyte: flash memory and advanced controllers cost more, so SSDs are typically more expensive per GB than HDDs. The statement that SSDs have moving parts is inaccurate, and claims of them being slower or cheaper per GB don’t reflect how these drives perform and are priced.
