The time it takes for a targeted data sector on a hard drive platter to rotate under the read/write head is called:
A. Transfer Rate
B. Seek Time
C. Settling Time
D. Rotational Latency
Answer: Option D
Solution (By JKSSB Mock Tests)
Rotational latency is the delay spent waiting for the spinning disk platter to bring the specific requested data sector directly beneath the read/write head.
Explanation:
SSDs have a limited number of program/erase cycles, especially TLC and QLC NAND, so they may wear out faster under heavy writes compared to HDDs and other media, though modern SSDs have good endurance.
