What benefit does RAID5 provide over RAID0?

RAID 5 provides a significant benefit in terms of data redundancy due to its use of parity. This configuration employs a scheme where data and parity information are distributed across all drives in the array. In the event of a single drive failure, the lost data can be reconstructed using the remaining drives and the parity information. This redundancy is crucial for protecting data integrity and ensuring availability, especially in environments where data loss can lead to severe consequences.

In contrast, RAID 0 does not provide any redundancy. It stripes data across multiple drives, which can enhance performance and increase storage capacity but leaves the system vulnerable to total data loss if one drive fails. RAID 5's ability to recover from a single drive failure while still effectively using storage space makes it particularly appealing for those prioritizing data safety without sacrificing too much performance.
