1. Suppose a disk drive has the following characteristics:
• 5 surfaces
• 1024 tracks per surface
• 256 sectors per track
• 512 bytes/sector
• Track-to-track seek time of 8 milliseconds
• Rotational speed of 7500 RPM.
a) What is the capacity of the drive?
b) What is the access time?
c) Is this disk faster than the one described in Question 2? Explain.
