Which of these choices provides the highest level of performance and redundancy? A) RAID 0 B) RAID 1 C) RAID 5 D) RAID 10
RAID 10 /RAID 0 is quite fast but provides no parity or mirroring information to recover from a drive loss and so it is not fault tolerant. RAID 1 is slightly slower because each write operation has to take place on each drive in the mirror before continuing. Although fast, RAID 5 stripes parity data across all drives and can more readily tolerate drive failures than the other types. A failed RAID 5 volume will still operate and can be rebuilt by simply replacing the failed drive. It will rebuild itself using the parity information stored on the other drives. RAID 10 (one zero or 1 + 0) provides the combination of speed and redundancy not found in other implementations. It combines the bit for bit real time redundancy not found in other implementations. It combines the bit for bit real time redundancy of mirroring (RAID 1) with the speed of striping data (RAID 0). The cost of implementation is higher due to the number of disks needed. RAID 10 is a hybrid as it combines the function of two RAID levels. Other combinations of this type exist but are outside the scope of the A+ certification exam objectives.
