RAID System calculating XOR operations
A). What level RAID system is this? RAID0, RAID1, RAID2, RAID3, RAID4, RAID5 or RAID6?
B. )Writing a new block 8 requires reading some number of disk blocks (=R), writing some number of disk blocks (=W) and performing some number of XOR operations (=N). For example, computing A xor B xor C would be considered 2 XOR operations. What are the values for R, W and N? Explain your answer.
