Compared with No Read Ahead, Write Through, and Direct, Read Ahead, Write Back, and Cached have
improved performance, but data consistency cannot be guaranteed.
If the supercapacitor is abnormal, when the write cache policy is set to "Write Back", the firmware will
implement "Write Through" for writing data; if the write cache policy is set to "Always Write Back", the
firmware write data will implement "Write Back".
