Question

Suppose a hard disk has 15000 rotations per minute (RPM) with data transfer rate of 5 × 10^6 bytes/sec. If the average seeks time of the disk is twice the average rotational delay and the controller’s transfer time is 10 times the disk transfer time. Calculate the average time (in milliseconds) to read or write a 512 byte sector of the disk?
