Mirrored stripes combining RAID 1 and RAID 0
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
RAID 0: Striping without parity, provides improved performance but no fault tolerance.
RAID 0 offers performance without redundancy; RAID 1 offers mirroring; RAID 5 and RAID 6 offer striping with single and double parity respectively. Common confusions include swapping mirroring and striping descriptions.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
RAID 0: Striping without parity, provides improved performance but no fault tolerance.
Why this is correct
RAID 0 uses striping across disks to increase performance but offers no redundancy; failure of any disk results in data loss.
RAID 1: Mirroring, duplicates data across disks, provides fault tolerance but reduces usable capacity by half.
Why this is correct
RAID 1 mirrors all data, giving redundancy; if one disk fails, the other has complete data.
RAID 5: Striping with distributed parity, requires at least three disks, tolerates one disk failure.
Why this is correct
RAID 5 uses block-level striping with distributed parity, allowing recovery from a single disk failure.
RAID 6: Striping with double distributed parity, requires at least four disks, tolerates two disk failures.
Why this is correct
RAID 6 extends RAID 5 with an additional parity block, allowing two simultaneous disk failures.
RAID 5: Mirroring with parity, provides high performance and fault tolerance.
Why it's wrong here
Incorrect — RAID 5 does not use mirroring; it uses striping with distributed parity. This description confuses RAID 5 with RAID 1+5 or RAID 10.
RAID 1: Striping without parity, maximizes storage capacity.
Why it's wrong here
Incorrect — RAID 1 is mirroring, not striping. This describes RAID 0.
Quick reference
| RAID Level | Min Disks | Fault Tolerance | Read | Write | Usable Capacity |
|---|---|---|---|---|---|
| RAID 0 | 2 | None | Excellent | Excellent | 100% |
| RAID 1 | 2 | 1 disk | Good | Moderate | 50% |
| RAID 5 | 3 | 1 disk | Good | Moderate | 67–94% |
| RAID 6 | 4 | 2 disks | Good | Lower | 50–88% |
| RAID 10 | 4 | 1 disk per mirror | Excellent | Good | 50% |
RAID is not a backup strategy — it protects against disk failure but not against accidental deletion, ransomware, or site-level events.
