Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0017] figure 1 It is a performance comparison chart of TLC, MLC and SLC; if the physical block of the same TLC process is forced to convert to the SLC process, it will drop to 1 / 3 of the original TLC original storage capacity; if the physical block of the same MLC process is forced to convert to the SLC process, then it will drop It is 1 / 2 of the original TLC original storage capacity, but the read and write performance has been greatly improved, and the space is ...

Abstract

The invention discloses a method for realizing dynamic acceleration areas of solid-state hard disks and a hard disk. The method is characterized by comprising the following steps of: at least dividing an acceleration partition in a solid-state hard disk of an MLC or TLC process, converting physical blocks of the acceleration partition into SLCs, preferentially writing a writing operation of the solid-state hard disk into the acceleration partition by an external controller, and directly returning writing success after the writing is completed; arranging a dynamic updating program in control of the solid-state hard disk and automatically updating data of the acceleration partition into a new space at the background, wherein the user space is a non-SLC area. Through converting partial MLC/TLC physical blocks into SLCs, higher reading/writing performance can be obtained; and meanwhile, the size of the acceleration partition is dynamically adjusted according to a proportion of a logic using space and a physical space of the disk, so that the effect of relatively high writing speed effect can be realized at user side.

Description

technical field [0001] The invention relates to a solid-state hard disk control technology, in particular to a method for realizing a dynamic acceleration area of ​​a solid-state hard disk and the solid-state hard disk. Background technique [0002] SSD (Solid State Drive) has been widely used in various occasions. With the evolution of NAND technology, from SLC to MLC, and then to TLC, its programming complexity is getting higher and higher. Correspondingly, the writing performance of NAND with the same capacity is in the decline. Therefore, for applications with certain requirements on the writing time, the writing performance of the MLC and TLC cannot meet the application requirements. For applications that write a large amount of data, the slow writing speed will also reduce the response speed of the application and seriously affect the user experience. Contents of the invention [0003] In view of the above defects, the purpose of the present invention is how to imp...
