Consider a disk with the following specifications: 512 bytes sector size, 8 double sided platters (2 surfaces per platter), 5000 tracks per surface, 100 sectors per track, average seek time of 10 msec, and the disk rotates at 5400 revolutions per minute (rpm). Which of the following is the correct combination of number of cylinders, average rotational delay, and transfer rate (if an entire track of data can be transferred per revolution of disk)?
A. 5000 cylinders, 5.55 milliseconds, 4.5 KB
B. 5000 cylinders, 4.5 milliseconds, 12 KB
C. 4000 cylinders, 5.55 milliseconds, 10 KB
D. 4000 cylinders, 2 milliseconds, 2.5 KB
