Question 5

a. Consider a disk drive with the following characteristics as shown in Table Q5:

Disk Capacity

# sectors per track32sectors per trackSector size1024bytes# platters5 platters# track per surface5K tracks per surfaceRotational speed5000 rpm.

i. Calculate the total disks storage capacity in Gigabyte.(CO2, PO3 4 marks)

ii. What is the data transfer rate in bytes per second for this drive once the head is positioned over the sector to be read?(CO2, PO3 3 marks)

iii. If the transfer rate of the disk is 2.95 MB/sec, calculate the disks rotation rate (in RPM).(CO2, PO3 4 marks)
