Abstract:
A storage system according to one aspect of the present invention includes a plurality of storage devices using flash memory as a storage medium. The flash memory used for the storage device may include flash memory configured to operate each cell as a cell capable of storing n-bit information or a cell capable of storing m-bit information (where n<m). The storage system may periodically acquire a number of remaining erasures form the storage device and predict the lifetime of the storage device by using the acquired number of remaining erasures and the storage device operation time. If the predicted lifetime is greater than a predetermined value (service life) a predetermined number of cells may be changed to cells capable of storing m-bit information.

Claim (Index 5):
The storage system according to  claim 4 , wherein:\n the storage system structures a plurality of RAID groups from the plurality of storage devices; and the storage controller is configured to:\n acquire the post-increase storage capacity calculated by each of the storage devices belonging to the plurality of RAID groups, and \n notify each of the storage devices belonging to the plurality of RAID groups of a minimum value of the acquired post-increase storage capacity of each of the storage devices, and \n the storage device that received the notification is configured to repeat, until the storage capacity reaches the notified minimum value, a process of changing the mode of the blocks operating in the first mode to the second mode.
