Summary:A method of accessing a Solid State Disk (SSD) and an SSD are provided, where the SSD includes: a cache (202), N physical channels (204), and flashes (203) mounted to the physical channels. The cache includes a plurality of strips. Each of the plurality of strips includes N sectors, N being an integer greater than or equal to 3. The method is applied to the SSD. According to the method, a data writing command for the SSD is received (S301); a first strip and a first sector that correspond to an LBA of data to be written carried in the data writing command are determined (S301); when the first strip is present in the cache (S302), the data to be written is written into the cache as data of the first sector (S303); and when the first strip is absent in the cache, the first strip is established and the data to be written is written into the cache as data of the first sector (S304).
