What is the primary feature of RAID 50?

RAID 50 is known for its combination of two fundamental RAID types: RAID 0 and RAID 5. In this configuration, RAID 50 takes advantage of block-level striping from RAID 0, which enhances performance by distributing data across multiple disks for quicker read and write operations. Alongside this, it implements the distributed parity features found in RAID 5, which provide fault tolerance by using parity information spread across the drives.

This distinctive interplay allows RAID 50 to offer improved performance due to the striping of data while still ensuring data protection against the failure of one drive in each RAID 5 set. The combination effectively balances both speed and redundancy, making RAID 50 suitable for environments where both high availability and performance are crucial.
