RAID 0 capacity: RAID 1 capacity: RAID 3 capacity: RAID 5 capacity: RAID 6 capacity: 2. Perform the same type of analysis as that of Table 11.2 (p 512; also on slide 53 of the Chapter 11 presentation from class, available online) for the following sequence of disk track requests: 27, 129, 110, 186, 147, 41, 10, 64, 120. Assume that the disk head is initially positioned over track 100 and is moving in the direction of decreasing track number.
