A non-volatile memory storage system is provided. The non-volatile memory storage system comprises a non-volatile memory cell array and a processor in communication with the non-volatile memory cell array. Here, the processor is configured to receive a write command to write data, where the write command comprises a logical address associated with the data. The processor is further configured to allocate a chaotic update block if the logical address is associated with a host file management data structure. After the allocation, the data are written to the chaotic update block.
