Explanation

According to the CHFI v11 objectives under Digital Evidence and Operating System Forensics, understanding RAID configurations is essential for both evidence acquisition and incident analysis. RAID 1, also known as disk mirroring, ensures data integrity and availability by duplicating identical data across two or more physical drives. Every write operation is simultaneously written to both drives, creating an exact replica of the data at all times. In the event of a single hard drive failure, RAID 1 allows the system to continue operating seamlessly using the remaining drive, with no interruption to data access and no data loss. This immediate failover capability is what ensures high availability and strong data integrity, making RAID 1 especially suitable for mission-critical systems such as databases and forensic evidence repositories. From a forensic perspective, investigators can still access complete and consistent data even after a hardware failure.
