RAID Level 1 utilizes which method for data storage?

RAID Level 1 employs disk mirroring as its primary method for data storage. In this configuration, data is duplicated across two or more disks, creating an exact copy. This mirroring approach enhances data redundancy, meaning if one disk fails, the system can continue to operate using the other disk with an identical copy of the data.

Disk mirroring is particularly beneficial for improving data reliability and availability. Because each piece of data exists on multiple disks, the risk of data loss due to hardware failure is significantly reduced. Additionally, this setup facilitates read operations, as data can be read from multiple disks simultaneously, potentially improving performance for read-heavy applications.

Understanding this method is crucial for network defense and data management. It helps in designing systems that prioritize data integrity and availability, key principles in network defense strategies.
