Abstract

PURPOSE: To write the data including the check data at a high speed by generating effectively the check data on the write data to be written into the disk drives forming a disk array.
CONSTITUTION: The write data transferred from a host computer 1 are stored in the buffer memories BM0-BM2 for each disk drive. A check data generating circuit 6 generates the check data based on the write data written in the memories BM0-BM2. Then the check data are sent to a check disk drive D3, and the write data are transferred to the corresponding disk drives D0-D2 respectively.
