To optimize application data performance, which RAID level should the administrator implement?

• A. RAID 0
• B. RAID 1
• C. RAID 5
• D. RAID 6

Answer: (C)

When considering which RAID level to implement for optimizing application data performance, RAID 5 is often favored due to its balance of data redundancy and performance. RAID 5 utilizes striping with parity, meaning that data is split into blocks and distributed across multiple disks, which enhances read performance. This configuration allows simultaneous access to multiple drives, speeding up data retrieval processes, which is particularly beneficial for applications requiring quick access to data. The parity data, which is distributed across the drives, also provides fault tolerance, allowing for the recovery of data in the event of a single drive failure without significant downtime. This balance of enhanced performance and redundancy makes RAID 5 a common choice for improving application data performance while also protecting against data loss. In contrast, other RAID levels, such as RAID 0, focus solely on performance through striping but offer no redundancy. RAID 1 provides mirroring, which improves read speeds but can slow down write operations since data must be duplicated across drives. RAID 6 offers additional data protection through the use of double parity but typically incurs a performance cost compared to RAID 5 because it requires more processing to manage the additional parity information. This understanding of RAID levels highlights how RAID 5 delivers both improved performance and data security, making
