What does the process of disk striping involve?

• A. Storing the same data on multiple disks for redundancy
• B. Dividing data into blocks and spreading them across multiple disks
• C. Mirroring data across two disks for security
• D. Compressing data before storage on the disk

Answer: (B)

The process of disk striping involves dividing data into blocks and spreading them across multiple disks. This technique enhances performance by allowing simultaneous read and write operations to multiple disks, which can significantly increase data transfer rates and improve overall system efficiency. When data is striped, it is segmented into smaller pieces, and these pieces are written across several disks in a round-robin fashion. As a result, when a system requests data, it can retrieve different parts from different disks simultaneously, minimizing bottlenecks that can occur when accessing a single disk. This method is commonly employed in RAID configurations, specifically RAID 0, where the primary objective is to boost performance rather than to provide redundancy or data protection. In contrast, other options like mirroring or redundancy approaches focus on data protection rather than performance, which is not the primary objective of disk striping. These different methods serve distinct purposes in data management, highlighting the unique value of striping in enhancing speed and efficiency.
