PROBLEM TO BE SOLVED: To provide a storage system and a data transfer method of the storage system, capable of obtaining higher data I/O performance even when hardware resources are limited.SOLUTION: A storage system comprises: a storage device which stores data used by an external device; a first temporary data storage unit and a second temporary data storage unit which temporarily store the data read from the storage device; and a control unit which selects first data transfer processing or second data transfer processing on the basis of contents of an I/O request when data read out from the storage device on the basis of the I/O request from the external device is transferred to the first data storage unit. In the first data transfer processing, the data is transferred from the storage device to the first data storage unit. In the second data transfer processing, the data is transferred from the storage device to the second temporary data storage unit and then transferred from the second temporary data storage unit to the first temporary data storage unit. |
