Example Embodiment
[0113] As a specific embodiment of the storage system data protection method provided by the present invention, the method includes the following steps:
[0114] In step S100, when data is written into the solid-state storage module, the data is controlled to perform RAID calculation to generate check block data.
[0115] Step S200: Detect the data volume of the data. When the data volume is greater than or equal to the stripe width of the solid-state storage module, step S300 is executed; when the data volume is less than the stripe width of the solid-state storage module, step S400 is executed.
[0116] Step S300, controlling the check block data to be written into the solid-state storage module.
[0117] Step S400, controlling the verification block data to be written into the backup module.
[0118] Here, it should be noted that the solid state storage module may be a solid state disk, and the backup module may be a hot spare disk. The following embodiments all use solid state disks...
