The invention provides a data writing method and a solid-state hard disk array (700). The SSD array is based on RAID system, including n SSDs (110N). When writing data to be written to the SSDs array (700), the data to be written is divided into N data blocks, corresponding to n SSDs (110N). After all N data blocks are stored in the corresponding solid-state hard disk (110N), FTL of N data blocks is refreshed to complete the writing of data to be written. When the SSD array (700) stores n data blocks, the power is cut off, and N data blocks are not written to the SSD array (700) successfully because the FTL of data blocks has not been refreshed, which ensures the atomicity of the write operation of N data blocks.
