Windows Server Administration Fundamentals — Question 155

Which of the following RAID levels provides best performance because data read and data write operations are not limited to a single disk, but to a set of disks?

Answer options

• A. RAID-1
• B. RAID-10
• C. RAID-0
• D. RAID-3

Correct answer: C

Explanation

RAID-0 is designed to enhance performance by striping data across multiple disks, which enables simultaneous read and write operations, thus maximizing throughput. In contrast, RAID-1 mirrors data for redundancy, RAID-10 combines mirroring and striping but may not achieve the same level of performance as RAID-0, and RAID-3 employs a dedicated parity disk, which can become a bottleneck.
