RAID 50 is a type of nested RAID level that utilizes the block-level striping of RAID 0 and has better write or I/O capabilities than standard RAID 5, along with improved fault tolerance. However, it utilizes more disk space for parity information.
RAID 50 is also known as RAID 5+0.
RAID 50 primarily provides higher data transfer rates and similar performance in smaller I/O requests. However, if two disks fail, the RAID 50 array cannot continue to function. It requires at least five drives to construct this array, and each disk spindle must be synchronized with each other. It dedicates 25% of RAID set space to parity information or stripes parity information across all RAID sets.
