Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a specific hard disk with a seek time of 5 ms, a rotational delay of 10 ms, and a transfer rate of 100 MB/s, calculate the total time to read a 100 MB file. Discuss any assumptions made.

💡 Hint: Break down the time components into their respective contributions.

Challenge 2 Hard

Illustrate how changing the addressing format from surface-wise to track-wise access would affect the data retrieval speed and the potential mechanical movements required.

💡 Hint: Consider how multiple accesses may require different levels of head movement.
