What is RAID 50?
RAID 50 is a type of nested RAID level, which means it is a combination of two different arrays. Components of RAID 50 RAID 50 is the conjunction of RAID 5 and RAID 0. It uses the disk striping ability of the RAID 0 with the distributed parity feature of RAID 5 to ensure that your drives work at optimum conditions.
What are the different RAID levels?
The following list explains the standard RAID levels (0, 1, 2, 3, 4, 5, 6) and popular non-standard and hybrid options (RAID 10). RAID 0, also known as a striped set or a striped volume, requires a minimum of two disks. The disks are merged into a single large volume where data is stored evenly across the number of disks in the array.
How many disks do I need for RAID 50?
RAID 50 requires an array with at least six disks — two RAID 5 arrays of three disks each. I like to use three or four disk RAID 5 sets in RAID 50 arrays. With RAID 5, as you increase the number of disks in the array, you increase the likelihood that you’ll experience total array failure as more than one drive fails at the same time.
