VerifiedData Backup Strategies

Nancy works as a network administrator for a small company. Management wants to implement RAID storage for the organization and use the appropriate RAID level for its backup plan that meets the following requirements:

  1. It has a parity check to store all information about the data across multiple drives.
  2. It helps reconstruct the data during downtime.
  3. It processes data at a good speed.
  4. It should not be expensive.

The management team asks Nancy to research and recommend the RAID level that best fits these requirements. Which RAID level should she suggest?

Explanation

RAID 3 stripes data across multiple drives and uses one dedicated parity drive. If a drive fails, the parity information and remaining data can reconstruct the lost data. Its striped layout improves transfer performance, while sacrificing only one drive’s capacity for parity rather than duplicating all data as mirroring-based RAID levels do.
