RAID level 5 works with any number of disk equal or greater than 3 and places a parity sum on one disks in the set to be able to recover from a disk failure. (Striped blocks with distributed parity.) The parity calculations are done in a RAID 5 set using XOR. We assume a small RAID 5 set of four disks and some data is written to it. On the first three disks we have the binary information 1010, 1100 and 0011, here representing some data, and now calculate the parity information for the…

(2006), the bigger the Beta value, the higher the influential factor by the particular independent variable. However, in this relationship, the influence power of independent variable is apparently low. Moreover, the relationship also deem insignificant because the significance level is at 0.3, which is above .05. H2: There…
