Method for reading and writing solid-state disk and solid-state disk thereof

Abstract

The invention belongs to the technical field of solid-state disks, and provides a method for reading and writing a solid-state disk and the solid-state disk of the method. In order to achieve the aims, the invention provides the method for reading and writing the solid-state disk. The method comprises the following steps: A, using the page size of flash memory of the solid-state disk to integrate write requests of an upper-layer service on the solid-state disk, B, using the page size of the flash memory of the solid-state disk to integrate a plurality of read requests of the solid-state disk, and C, adopting an IO request queue to rank the write requests and the read requests of the solid-state disk. Therefore, according to the method for reading and writing the solid-state disk and the solid-state disk of the method, the application of the solid-state disk in the Internet is optimized, and the use efficiency of the solid-state disk is improved.

Description

technical field [0001] The invention relates to the technical field of solid-state hard drives, in particular to a method for reading and writing solid-state hard drives and the solid-state hard drives. Background technique [0002] SSD (Solid State Disk, solid state drive) is a computer external storage device based on permanent memory, such as flash memory, or non-permanent memory, SDRAM (Synchronous Dynamic Random Access Memory, synchronous dynamic random access memory). It has fast reading and writing speed, low power consumption, no noise, anti-vibration, low heat, small size, large working range, and is widely used in various fields. The Internet is currently a booming field. Its business features are large data volume, sensitive to the response time of read requests, and require relatively large peak IOPS (Input / Output Operations Per Second, read and write operations per second) for write requests. times). Because SSD can solve the Internet business's fast response ...

AI Technical Summary

Problems solved by technology

However, in the prior art, the method of reading and writing solid-state hard drives in Internet applications cannot avoid the shortcomings of solid-state hard drives according to the characteristics of Internet services.

[0003] In summary, the existing SSD read and write technology obviously has inconvenience and defects in actual use, so it is necessary to improve it.
