A storage control apparatus writes n pieces of data (here, n is an integer greater than 1) in a first memory apparatus, and reads the n pieces of written data from the first memory apparatus. A parity calculation unit calculates parity based on divided data extracted from each of the n pieces of data for each certain size, and stores the calculated parity in a second memory apparatus. A read control unit restores, in reading the n pieces of data from the first memory apparatus, at least one of the n pieces of data instead of reading it from the first memory apparatus but using other data having been read from the first memory apparatus among the n pieces of data and the parity stored in the second memory apparatus.
