Hi,
RAID stands for Redundant Array of Independent Disks. It is not the oracle terminology, it is implemented at hardware level.
In RAID config many disks are joined together in an array to create a huge storage area. Different RAID levels are available to fulfill different requirements. Like RAID 0 can be impelemented to mirror the whole disk to another, in this case the requirement for disks would be double. RAID 1 can be used to stripe data on multiple disks. RAID 4,5 are present to store data as well as some parity information to reconstruct the data in case of failure. It totally depends upon business requirements what type of configuration is required.
For oracle, RAID 0+1 combination is most better, where data will be mirrored as well as striped on different disks.
I hope it will help.
