Select the redundancy level for which you would like to prepare this disk folder.

Redundant	Redundant storage uses a mix of RAID types across disk tiers, providing redundancy for your data and preventing data loss in the event of disk failure. Standard redundant storage uses a mix of RAID 10 and RAID 5 storage by default, but can also be configured by disk tier to use RAID 10 Dual Mirror and RAID 6 storage.
Non-Redundant	Non-Redundant storage user RAID 0 storage and does not provide data redundancy.
