SK0-004 · Question #255

Which of the following BEST describes RAID 0?

The correct answer is D. Striping. RAID 0 writes data in stripes across two or more drives with no parity or mirroring, maximizing performance at the cost of all redundancy.

Why each option

RAID 0 writes data in stripes across two or more drives with no parity or mirroring, maximizing performance at the cost of all redundancy.

AStriping with parity

Striping with parity describes RAID 5, not RAID 0, which has no parity at all.

BStriping with mirroring

Striping with mirroring describes RAID 10 (RAID 1+0), which combines RAID 1 mirroring and RAID 0 striping.

CMirroring

Mirroring alone describes RAID 1, which duplicates data identically across two drives without striping.

DStripingCorrect

RAID 0 splits data into blocks and writes them sequentially across all drives in the array, a technique called striping. No parity or redundancy is maintained, meaning the failure of any single drive results in total data loss. The sole defining characteristic of RAID 0 is striping.
