Suppose that you have 10 20 GB disk drives, each of which has 500 sectors per track. Suppose that you want to create a virtual 200 GB drive by striping the small disks, with the size of each stripe being an entire track instead of just a single sector.
(a) Suppose that the controller receives a request for virtual sector M. Give the formula that computes the corresponding actual drive and sector number.
(b) Give a reason why track-sized stripes might be more efficient than sector sized stripes.
(c) Give a reason why track-sized stripes might be less efficient than sector sized stripes.
