Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] see figure 1 , in the first embodiment of the present invention, a solid-state hard disk 100 is provided, including:

[0031] The first integration module 10 is used to integrate the write request of the upper-layer business of the solid-state hard disk 100 in units of the page size of the flash memory of the solid-state hard disk 100;

[0032] The second integration module 20 is used to integrate multiple read requests of the solid-state hard disk 100 in units of the page size of the flash memory of the solid-state hard disk 100;

[0033] The sorting module 30 is configured to sort the wr...

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 ...
