CompTIA DataSys+ (DS0-001) — Question 20

Which of the following types of RAID, if configured with the same number and type of disks, would provide the best write performance?

Answer options

• A. RAID 3
• B. RAID 5
• C. RAID 6
• D. RAID 10

Correct answer: D

Explanation

RAID 10 combines the benefits of both RAID 1 and RAID 0, allowing for high write speeds due to striping while also providing redundancy. RAID 3, 5, and 6 introduce parity calculations which can slow down write performance compared to RAID 10's straightforward mirroring and striping approach.
