Which RAID configuration is known for striping without redundancy?

RAID 0 is known for striping without redundancy, making it a popular choice for scenarios where performance is prioritized over data protection. In this configuration, data is split into blocks and distributed evenly across multiple disks, allowing for improved read and write speeds since multiple drives can be accessed simultaneously. However, this lack of redundancy means that if any single drive in the array fails, all data on that RAID 0 array is lost. This risk is an important consideration when deciding whether to implement RAID 0, as it is best suited for applications that can tolerate data loss, such as temporary data storage or performance-sensitive tasks where backups are implemented separately.

In contrast, RAID 1 provides redundancy by mirroring data across two or more disks, thus ensuring that data remains intact in case of a drive failure. RAID 5, on the other hand, combines striping and parity for fault tolerance while allowing for data recovery in the event of a single disk failure. RAID 10, which is a combination of RAID 1 and RAID 0, offers both redundancy and improved performance but requires a minimum of four disks. Each of these configurations serves different needs, but only RAID 0 operates purely on striping without incorporating any redundancy measures.
