How is the storage capacity of RAID calculated?

RAID 0: The storage capacity is the capacity of N* smallest hard disks (N is the number of hard disk drives, not less than 2).

RAID 1: The storage capacity is the capacity of the smallest hard disk.

RAID 5: The storage capacity is the capacity of (N-1)* smallest hard disks (N is the number of hard disk drives, not less than 3).

RAID 6: The storage capacity is the capacity of (N-2)* smallest hard disks (N is the number of hard disk drives, not less than 4).

Single Disk: The capacity of each hard drive is independent.

JBOD: The storage capacity is the sum of the capacity of all hard disk drives.
