Storage system

A storage system, comprising:

• a plurality of non-volatile storage devices configured to be able to perform writing and reading of data independently, each of the plurality of storage devices being divided into a plurality of blocks and erasing data in units of a block, each of the plurality of blocks having a size that is unique for each storage device;
• a control device configured to control writing of data and reading of data on the plurality of storage devices;
• and
• a non-volatile feature information memory configured to store feature information including a start address and a size of each of the plurality of blocks for each of the plurality of storage devices, wherein
• the control device includes
• a setting unit configured to set a plurality of chunks obtained by dividing a storage region for each of the plurality of storage devices, and set a plurality of stripes obtained by dividing storage regions of all of the plurality of storage devices for all of the plurality of storage devices, and
• a writing/reading unit configured to manage data stored in the plurality of storage devices in units of the stripes, wherein
• at a time of initialization, the setting unit
• acquires the feature information for each of the plurality of storage devices from the non-volatile feature information memory,
• sets a size of a chunk that is unique for each storage device on the basis of the acquired feature information, and
• sets, based on the acquired feature information, each of the chunks so that the chunk for at least one of the plurality of storage devices includes the entirety of one or more blocks, and sets each of the stripes to include two or more of the chunks.
