Tips
The capacity for the HDD model number field is larger than that for the
Extent x field. This is because the capacity for the model number field
indicates the total capacity of the used HDD while the capacity for the
Extent x field indicates the capacity resulting from subtracting the capacity
of the management area used by the disk array controller from the total
capacity.
