Abstract:
1. A storage apparatus transferring data upon reading data from or writing data to a plurality of storage units each having a unique transfer rate, the storage device comprising: a controlling unit that controls transferring of data at a fixed rate, the data read from or written to a storage unit; a detecting unit that is connected to the storage unit and detects a transfer rate of the storage unit; and a converting unit, which is provided between the storage unit and the controlling unit, determines whether the transfer rate detected by the detecting unit is equal to the fixed rate, and allows the data read from or written to the storage unit to pass through without accumulating when the transfer rate is equal to the fixed rate, while interconverting the transfer rate and the fixed rate by accumulating the data read from or written to the storage unit when the transfer rate is not equal to the fixed rate.
