Abstract
Deterioration of compression throughput including a decompression check after data compression is suppressed. Provided is a storage system including an interface and a controller. The controller includes a compression circuit configured to generate compressed data by compressing received data received via the interface; and a decompression circuit configured to decompress the compressed data before storing the compressed data in a storage drive to confirm data consistency. The compression circuit sequentially executes a compression task of the received data, sequentially generates packets of the compressed data, and transfers the packets to the decompression circuit. The decompression circuit decompresses the received packet in parallel with the compression task.
