What is the approximate data transfer rate of a typical 7200 RPM hard disk drive?
A. 1-2 GB/s
B. 50-80 MB/s
C. 100-200 MB/s
D. 500-600 MB/s
Answer: Option C
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.
Explanation:
The read/write head contains electromagnetic coils that read data by sensing magnetic fields and write data by changing the magnetic polarity on the platter surface.
Explanation:
Data is stored on the platters, which are circular disks coated with magnetic material. The read/write head reads and writes data to the platters.
