Classification: CPC G | IPC G

Claim 8:
9. The storage system according to claim 2, wherein
the processor acquires the encoded data from the storage device, or decompresses compressed data acquired from the storage device into the encoded data,
for each of a plurality of pieces of encoded data acquired from the encoded data, the processor
determines a decompression operation scale of the encoded data based on a feature of the encoded data, and
executes a decompression operation according to the determined decompression operation scale to convert the encoded data into decoded data,

the processor generates decoded data of the data based on a plurality of pieces of decoded data generated for the plurality of pieces of encoded data,
for each of the plurality of pieces of encoded data,
determination of a decompression operation scale is to select a decompression route from a plurality of decompression routes which have different decompression operation scales and in each of which a decompression operation is executed, and
the encoded data is converted into decoded data in the selected decompression route.
