6.14.2 [5] <6.9> RAID 1 mirrors data among several disks. Assuming that inexpensive disks have lower MTBF than expensive disks, how can redundancy using inexpensive disks result in a system with lower MTBF? Use the mathematical definition of MTBF to explain your answer. For each of the activities listed in the table, will RAID 1 help better achieve their goals? | |
