Technical Field

Background

In order to increase the storage capacity of a computer device, a plurality of disks are often mounted in the computer device. The multiple disks loaded in a computer device are typically different types of disks due to storage speed and storage cost considerations. The computer device can adopt different data writing methods according to the difference of the residual capacity and the writing speed of different types of disks loaded by the computer device. A common data writing method is to write data blocks to a disk with a large remaining capacity or to write data blocks to a disk with a high operating speed. Writing data blocks to a disk with a large remaining capacity may cause a large number of data blocks to wait to be written to the disk with the large remaining capacity, resulting in a slow speed of writing data blocks. Writing a data block into a disk with a faster operating speed may cause the disk with the faster operating speed to store too many data blocks, resulting in a smaller remaining capacity of the disk with the faster operating speed, and thus a situation of unbalanced load of multiple disks may occur.

The computer device executes the data writing program to write the data block b to be written into the mechanical hard disk C, and then executes the data writing program to write the data block a to be written into the mechanical hard disk C.
