RAID types are illustrated below.
In the following illustration, the following identifier is used:
A, B, C, D, E, and F-represent data blocks.
P1, p2, p3-indicates the parity information block
RAID 0
RAID 0 features:
At least two disks are required.
Distribution of data entries
No redundancy and optimal performance (no image or verification information is stored)
It cannot be used in scenarios with high data security requirements.
