Abstract: A file processing method and a storage device for storing a file in a redundant array of independent disks (RAID) are disclosed. In this method, the storage device divides received F files into multiple data blocks, and obtains a first matrix with T rows according to the multiple data blocks. Data blocks belonging to one file are located in one row of the first matrix. The storage device then writes a stripe, which consists of data blocks in each column in the first matrix and a check block that is obtained by computing according to the data blocks in the column, into the RAID. Using the file processing method, the storage device can write one file into one disk of the RAID while ensuring security of file storage, thereby achieving a better energy saving effect when the file is read.

Abstract: A file processing method and a storage device are disclosed. In the method, a storage device receives T files that are to be stored in the RAID, and determines a sequence number of a check block in a stripe of the RAID. The storage device repeatedly obtains a data block of the Kth file in the T files as the Kth data block in the stripe, where a value of K progressively increases from 1 to T, and the value of K is not equal to the sequence number of the check block in the stripe. After computing the check block according to data blocks, the storage device writes, into the T disks, the data blocks and the obtained check block in the stripe. By using the foregoing method, one file can be written into one disk of the RAID while ensuring security of file storage.
