Challenge Problems
Push your limits with advanced challenges
A disk has a seek time of 7 ms, rotational latency of 5 ms, and transfer time of 3 ms. If you want to improve the access time by 30%, what should the new maximum access time be?
💡 Hint: Calculate the 30% reduction based on current access time.
If a disk operates at 10000 RPM and has a seek time of 4 ms, what is the total access time if the rotational latency is 6 ms and transfer time is 2 ms?
💡 Hint: Remember to first calculate the average rotational latency.
