RAID SYSTEM USING SEMICONDUCTOR STORAGE DEVICE AND METHOD FOR CONTROLLING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a RAID system using a semiconductor storage device which averages a mechanical load and an electric load which are assumed with respect to semiconductor memories which distribute and store data.

SOLUTION: The RAID system 100 which transfers data to/from host equipment 200 is equipped with: a plurality of semiconductor storage devices 10 having a plurality of semiconductor memories mounted thereon; a semiconductor memory selection part 20 which selects combination of the semiconductor memories when the data are distributed and stored in the plurality of semiconductor storage devices 10; and a memory control part 30 which access a semiconductor memory selected by the semiconductor memory selection part 20, in response to the request of the host equipment 200. The semiconductor memory selection part 20 selects the combination of the semiconductor memories 20 so that the mechanical load to be received by the semiconductor memories is averaged.
