Abstract
Solid-state drives (SSD) and a data access method for SSD are provided. The method includes the following. Cache acquired data-to-be-written to a preset write cache module. Rank the data-to-be-written in the write cache module according to a least recently used page (LRU) algorithm. When data storage amount of the write cache module reaches a preset value, determine a preset number of replacement data among the infrequently used data-to-be-written according to a preset cache replacement algorithm. Write the replacement data into a flash memory of the SSD. Implementations of the present disclosure can decrease effectively the number of times of rewriting on a flash memory of the SSD, thereby reducing effectively a write amplifying problem of the SSD during data access.
