Data and parity data configure a stripe. A plurality of stripes configure a parity group allocated with a plurality of storage drives to store the parity group. A first parity group allows the number of storage drives allocated to the parity group to be equal to the number of data pieces configuring each stripe. A second parity group allows the number of storage drives allocated to the parity group to be larger than the number of data pieces configuring each stripe and allows data for each stripe to be distributed and stored in different combinations of storage drives. When the first parity group is converted to the second parity group, a storage drive is added so that it is allocated to the parity group. Data is moved to ensure a free area."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storage system and control method of the same","description":"A storage system including a storage controller and a plurality of storage drives generates parity data from data.
