A. Higher capacity
B. No moving parts, faster access
C. Lower cost per GB
D. Longer lifespan
Answer: Option B
Solution (By JKSSB Mock Tests)
SSDs have no moving parts and use flash memory, providing much faster read/write speeds and lower latency compared to HDDs, which rely on spinning platters and mechanical heads.
Explanation:
Magnetic tape offers the lowest cost per gigabyte among these, making it ideal for archival and backup. HDDs are also used but tape is cheaper for large volumes.
