A storage control device includes a first processor, a second processor, and transfer units for transferring data from the first processor to the second processor. The first processor receives a write request for writing first data from a first device and sequentially transmits the first data, additional data, and pieces of dummy data. A number of the pieces is same as a number of the transfer units. The first processor notifies the first device of completion of the writing upon receiving an acknowledgement for a last transmitted piece of dummy data. Each transfer unit includes a third processor. The third processor receives the additional data from a preceding processor, and transmits an acknowledgement to the preceding processor upon storing the received additional data. The third processor receives one piece of dummy data from the preceding processor, and transmits an acknowledgement to the preceding processor upon storing the one piece.
