What is the best RAID configuration for multiple data disks to increase IO throughput?
  • A.
    RAID 1 (Mirroring)
  • B.
    RAID 5 (Striped with parity)
  • C.
    RAID 0 (Striped without parity)
  • D.

  • Answer & Explanation
  • Report
Answer : [C]
Explanation :
A. Incorrect: RAID 1 mirroring is designed for redundancy but is not necessary because disks in Azure are already replicated three times in storage. Mirroring also does not increase IO throughput.
B. Incorrect: RAID 5 disk striping with parity is meant for redundancy and performance but is not necessary because disks in Azure are already replicated three times in storage.
C. Correct: RAID 0 disk striping without parity allows the operating system to spread IO across multiple disks, which can increase overall IO throughput.
D. Incorrect: Software RAID configurations are supported in Azure virtual machines.
