Consider a disk system with the following properties:

There are 216 tracks on 4 double-sided platters. Each track contains 50 sectors on an average. Each page corresponds to 5 sectors. The size of each sector is 28 bytes. Average seek time is 22.67 ms. Each random seek costs 1 ms to set up.

(a) How many tracks can the arm assembly sweep over in 1 ms? (b) Suppose the time to write 1 page of data is 0.8 ms. What is the approximate revolution rate of the disk in rpm (i.e., revolutions per minute)? (c) Estimate the total disk capacity in bytes.
