Correct Answer: A
Explanation/Reference:
Explanation:
RAID-0 is faster than RAID-5 since RAID-0 is striping without parity, while RAID-5 uses parity which makes it slower.
Incorrect Answers:
B: RAID-3 uses byte-level parity. The Data striping over all drives and parity data held on one drive. If a drive fails, it can be reconstructed from the parity drive.
C: With RAID-0 the data striped over several drives. No redundancy or parity is involved. If one volume fails, the entire volume can be unusable. It is used for performance only.
D: RAID-4 uses block-level parity. The Data striping over all drives and parity data held on one drive. If a drive fails, it can be reconstructed from the parity drive.
