Abstract: This storage system includes a processor, a memory, a storage drive, and an interface device. The storage drive determines a size of transfer data based on an offset value which is a value relating to a size between the beginning of a storage area in the memory for the transfer of the data to be transferred to the interface device and the beginning of the partition of the memory to which the beginning of the storage area belongs, and then transfers data to be transferred, which has the determined size, to the interface device. The interface device divides the transferred data into packets and transfers these packets to the processor. The processor then stores the packets transferred from the interface device in the memory on a unit of a partition.

Abstract: A storage apparatus includes: a controller; and a plurality of storage drives, wherein the controller issues a read command for specifying a value associated with an error correction mode to a first storage drive of the plurality of storage drives, the first storage drive selects the error correction mode associated with the value specified by the read command from a plurality of error correction modes, the plurality of error correction modes include a first error correction mode and a second error correction mode with a higher correcting capability and a longer maximum delay time than those of the first error correction mode, and the first storage drive executes a read of data from a storage medium in the selected error correction mode.
