    You just missed RAID levels 3 and 4, that use byte and block level stripping respectively.
    RAID levels 0 through 6 are also known as standard RAID levels, while combination of any two of them, just like RAID 10, are knows as hybrid RAID or Nested RAID.

    • In enterprise level we are not using RAID 3. Even standalone boxes have 0,1,5 but we can’t find 3 now days. From storage level there will be 4 and DP ( Dynamic Provisioning or it mean thin provisioning ) from Netapp stroage. Same from Hitachi Raid 5,6, 1+0 are used it will differ according to vendors.
