What is the approximate data transfer rate of a typical 7200 RPM hard disk drive? MCQ with Answer and Explanation

What is the approximate data transfer rate of a typical 7200 RPM hard disk drive?
A. 50-80 MB/s
B. 100-200 MB/s
C. 500-600 MB/s
D. 1-2 GB/s
Answer: Option B
Solution (By JKSSB Mock Tests)
Modern 7200 RPM HDDs typically have sustained transfer rates in the range of 100 to 200 MB/s, depending on density and technology. SSDs are much faster.
