Abstract

Disclosed is a method for writing data into a solid-state storage device. The method comprises: receiving a data writing request; based on the data writing request, determining that the data writing request is a first type, a second type or a third type; when the data writing request is the first type, writing data corresponding to the data writing request into a first storage region of the solid-state storage device; when the data writing request is the second type, writing the data corresponding to the data writing request into a second storage region of the solid-state storage device; and when the data writing request is the third type, writing the data corresponding to the data writing request into a third storage region of the solid-state storage device, wherein the first type indicates that the data written according to the data writing request is frequently updated, the second type indicates that the data written according to the data writing request is rarely updated, and the third type indicates that the updating property of the data written according to the data writing request is different from the indication of the first type or the second type. Furthermore, disclosed are a system for writing the data into the solid-state storage device and the storage device.

Description

technical field [0001] The present invention relates to a solid storage device (Solid Storage Device, SSD), and more specifically, the present invention relates to a method and device for writing data into a solid storage device and a storage device implementing the method. Background technique [0002] Similar to mechanical hard disks, solid-state storage devices are also high-capacity, non-volatile storage devices used in computer systems. A solid-state storage device generally uses a flash memory (Flash) as a storage medium. High-performance solid-state storage devices are used in high-performance computers. [0003] In a storage device using flash memory, data storage space is generally organized into blocks and / or pages, and each storage block may include multiple pages. Data can be written in units of pages. However, when data is updated, even if the data of a single page is updated, the entire block needs to be erased first, and then the original data and updated d...
