Raid 2 vs raid 1
What is the difference between RAID 0 and RAID 1?
There is no doubt that RAID 0 provides better storage capacity. Since there is no redundancy, the total storage that you can use for the RAID 0 unit is the sum of all individual disk storage capacities. However, in a RAID 1 array, the total storage capacity is equal to one hard disk. For instance, you have 2 hard disks with 500GB.
What is raid and how does raid work?
This part will introduce the definition and key features of RAID. RAID 1 is known as a mirrored volume that also requires 2 or more disks. It contains a copy of the data on the disks. This configuration owns high data security because it provides fault tolerance and redundancy.
Why is there no Raid 2 for hard disk drives?
With all hard disk drives implementing internal error correction, the complexity of an external Hamming code offered little advantage over parity so RAID 2 has been rarely implemented; it is the only original level of RAID that is not currently used.
