Example Embodiment

[0018] In view of the problems in the prior art, the present invention proposes a solid-state hard disk read and write solution, which can improve the read-write efficiency of the solid state hard disk.

[0019] In order to make the technical solution of the present invention clearer and more comprehensible, the following further describes the solution of the present invention in detail with reference to the accompanying drawings and embodiments.

[0020] figure 1 It is a flowchart of an embodiment of a method for reading and writing a solid-state hard disk of the present invention. Such as figure 1 Shown, including:

[0021] Step 11: When receiving any request, the solid-state drive determines whether the request is a read request, an asynchronous write request or a synchronous write request; if it is a read request, the request is added to the read request queue and ranked last; If it is an asynchronous write request, the request is added to the asynchronous write request queue an...

Abstract

The invention discloses a solid-state disk read-write method which includes that a solid-state disk determines if a request is a read request, an asynchronous write request or a synchronous write request when any request is received; the request is added to a read request queue and is arranged in the last place if the received request is the read request; the request is added to a asynchronous write request queue and is arranged in the last place if the received request is the asynchronous write request; the request is added to a synchronous write request queue and is arranged in the last place if the received request is the synchronous write request; and the solid-state disk processes every request in every queue in sequential order. The invention also discloses a solid-state disk. According to the technical scheme of the solid-state disk read-write method and the solid-state disk, the read-write efficiency of the solid-state disk can be improved.

Description

technical field [0001] The invention relates to hard disk technology, in particular to a method for reading and writing a solid state hard disk and a solid state hard disk. Background technique [0002] In the existing hard disk reading and writing methods, read requests and write requests are put into the read request queue and write request queue of the hard disk respectively, and the requests in each queue are processed in sequence according to the logical position of the requested data in the hard disk Sort. [0003] That is to say, the requests in the read request queue are sorted according to the logical position of the data to be read in the hard disk, and the requests in the write request queue are sorted according to the logical position of the data to be written in the hard disk Sort. [0004] Hard drives can generally be divided into two categories, mechanical hard drives and solid-state drives. Among them, the mechanical hard disk refers to the traditional ord...
