Which RAID level is known for disk striping without fault tolerance?

RAID Level 0 is recognized for disk striping without incorporating any fault tolerance. In this configuration, data is divided into blocks and striped across multiple disks, which enhances performance due to improved read and write speeds. However, since there is no redundancy or mirroring employed in RAID 0, if one disk fails, all data in the array becomes inaccessible. This makes RAID 0 an optimal choice when performance is prioritized over data protection, such as in environments where speed is critical and data loss is an acceptable risk.

The other RAID levels in the choices involve various forms of data redundancy or fault tolerance. RAID Level 1, for instance, utilizes mirroring to provide duplicate copies of data for fault tolerance. RAID Level 3 employs byte-level striping with a dedicated parity disk, offering some fault tolerance but not as efficiently as other levels. RAID Level 5 incorporates block-level striping with distributed parity, ensuring both performance and fault tolerance. Thus, RAID Level 0 stands out specifically for its combination of striping and lack of fault tolerance.
