RAID 0 utilizes a configuration known as striping, where data is divided into blocks and spread across multiple drives. This method enhances performance significantly since multiple disks can be read from and written to simultaneously, which increases data throughput rates. However, RAID 0 does not provide any fault tolerance; if one drive fails, all data in the array becomes inaccessible, as data is not duplicated or protected in any way.

In contrast, other RAID levels, such as RAID 1, RAID 5, and RAID 10, incorporate some form of redundancy or error correction, which protects against data loss in the event of a drive failure. RAID 1 mirrors data between two drives, RAID 5 uses parity information for fault tolerance, and RAID 10 combines mirroring and striping to provide both performance and redundancy. Therefore, RAID 0 stands out for its pure focus on speed without any measures to safeguard data integrity.
