In RAID 50 implementation, large arrays are formed by combining parity and block striping of RAID 5 with simple block striping of RAID 0. It is basically a RAID 0 array that is striped across RAID 5 elements and requires minimum of 6 drives to configure. A RAID 50 array might fail, rendering your data inaccessible. In such situations, you need to replace the array and call Data Recovery Service experts to recover lost data efficiently.
An Example
Generally, RAID 50 proves to be more fault-tolerant than its counterpart RAID 05, but it can fail. To illustrate, consider that you use three collections of RAID 5 sets, each with storage capacity of 180 GB. These sets are striped together so that to make total array of capacity 540 GB.
In the setup described above, the array will remain intact if one drive from each of the RAID 5 sets fail and will not cause any data loss. But until the failed drive is replaced, the entire array remains at single point of failure. It means that after the first drive failure, the remaining drives should not fail to prevent array failure. If any of the remaining drives fail, the array will fail.
The fault tolerance level of the array also depends on how the array is configured. If you construct three RAID 5 sets containing seven drives each, it will provide you good capacity, but provide fault-tolerance of up to three drives. On the other hand, an array with seven RAID 5 sets containing three drives each will provide lower storage capacity but high fault tolerance of up to seven drives. A reliable construction could be an array with three RAID 5 sets containing six drives each and a hot space that could provide immediate rebuilding of array on failure.
