A RAID system to transfer data to and from host equipment includes a semiconductor storage unit, a semiconductor-memory selector, and a memory controller. The semiconductor storage unit includes two or more semiconductor memories, a mounting board, and solder joints. The semiconductor memories are mounted on the mounting board. The solder joints are between the semiconductor memories and the mounting board. The semiconductor-memory selector selects a combination of the semiconductor memories to dispersively record the data in the semiconductor storage unit. The memory controller accesses the combination in response to a request of the host equipment. In addition, the selector selects the combination so that mechanical loads received by the semiconductor memories are averaged. |
