A hard disk contains 16 platters. The data is recorded on both surfaces of each platter. Each surface has 4,000 tracks. A track contains 1,000 sectors and each sector stores 4,096 bytes.
What is the capacity (expressed in Megabytes and Gigabytes) of one cylinder?
What is the capacity (expressed in Megabytes and Gigabytes) of the entire hard disk?
The above drive has the average seek time of 8 milliseconds [ms]. The disk revolves with the speed of 10,800 revolutions per minute.
Compute the average rotational delay (latency time).
Compute the transfer time for 400 sectors.
Compute the total disk access time which is the sum of the three times: the average seek time, the average rotational delay (latency time), and the transfer time for 400 sectors.
