Abstract
A flush method of a solid-state drive (SSD) comprises mapping a group of data to multiple segments of a mapping table; generating a recording table for recording a total value and multiple count values corresponding to the multiple segments; when one of the data is written, increasing one of the multiple count values corresponding to one of the multiple segments of the one of the data by a number, and increasing the total value by another number; determining whether the one of the multiple count values is greater than one of multiple optimized thresholds corresponding to the one of the multiple count values; and executing a flush operation to write the one of the multiple segments into a memory and restoring the mapping table if the one of the multiple count values is greater than the one of the multiple optimized thresholds.
