Question: 1) Consider a disk with an advertised average seek time of 3ms, rotation speed of 20,000rpm and 512 byte sectors with 500 sectors per track.

1) Consider a disk with an advertised average seek time of 3ms, rotation speed of 20,000rpm and 512 byte sectors with 500 sectors per track. Suppose we wish to read a file consisting of 2000 sectors.

a) Assuming that the data is stored as compactly as possible so that we only need one seek time to locate the first track and no additional seek time is needed, calculate the total transfer time.

b) Assuming that the data is spread amongst disparate tracks and sectors, so the time to read the next sector requires a new seek time, calculate the expected total transfer time.
