Abstract
A method for transmitting data between an information processing device and a storage device, in which the storage device includes a buffer memory and flash chips, includes: receiving a first write request including data to be written and an address used for the flash chip of the storage device; allocating a first memory unit in the information processing device for the first write request; sending a write command including data, the address used for the flash chip of the storage device and address used for the buffer memory, to the storage device, in which the address used for the buffer memory corresponds to the first memory unit; receiving a message indicating the performing of the write command by the storage device has been completed, from the storage device; and releasing the first memory unit.
