I am using a promox server with the following raid-RAIDZ-3. A variation on RAID-5, triple parity. Requires at least 5 disks. It works awesome for my VMs. It protects me fully if one disk goes down.
Raid 5 does this natively, how is this some amazing feature?
RAID 5 is single parity.
RAID 6 is double parity.
RAID 7 is triple parity.
This is RAID 7.
Sorry, I could've swore this said protects from 1 drive failure....
