Question 1
A hard disk has 5 platters and maintains a consistent bit density of 512 bits/sq inch. If each platter has a diameter of 6 inches, calculate the total data storage capacity.
💡 Hint: Use the area formula for circular disks and think about how density translates to storage.
Question 2
If a movable head disk system has a seek time of 10 ms and a rotational latency of 5 ms, what is the total average access time?
💡 Hint: Simply add the two times for average access.
