Which of the following RAID levels offers a balance between performance and data redundancy?

RAID level 5 is a popular choice for striking a balance between performance and data redundancy. This level uses striping, like RAID 0, which improves performance, but it also incorporates parity for redundancy. The use of parity allows for the reconstruction of data in the event of a drive failure, enhancing data protection while still providing improved read and write capabilities.

RAID 5 requires a minimum of three drives and distributes the parity information across all drives in the array. This distribution helps to ensure that no single drive becomes a bottleneck, thus allowing for efficient read speeds. However, it should be noted that when a drive fails, the performance can be momentarily degraded during the rebuild process, but RAID 5 still offers a favorable compromise when considering both speed and data integrity.

In contrast, RAID 0 offers no redundancy at all, focusing solely on performance by striping data across multiple disks without any form of error correction. RAID 1 provides data redundancy by mirroring data across two drives, but it does not enhance overall system performance as effectively as RAID 5, which achieves both goals. RAID 10, while also offering redundancy through mirroring and striping, typically requires more drives and is therefore not as space-efficient as RAID 5
