Problems solved by technology

This method first needs to perform operations such as device registration and formatting on the solid-state hard disk in the system. At the same time, there are multiple mappings of address relationships, which leads to low access efficiency and insufficient flexibility.
[0003] In summary, the existing SSD access technology obviously has inconvenience and defects in actual use, so it is necessary to improve it

Abstract

The invention is applicable to the storage technical field and provides a method for accessing a solid state disc and the solid state disc of the method. The method includes the following steps that the step of establishing is performed, and multiple storage pools of preset sizes are established in the storage space of the solid state disc; the step of storage is performed, and data are written into the storage pools and key words are configured for the storage pools into which the data are written; the step of accessing is performed and the data in the corresponding data pools are accessed by means of the key words. Therefore, the flexibility and the efficiency of reading and writing accessing of the solid state disc are improved.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method for accessing a solid-state hard disk and the solid-state hard disk. Background technique [0002] The current usage of solid-state hard disk is as follows. Solid-state hard disk has FTL (Flash translation layer, address translation layer) management logical page address (LPA, Logical Page Address) to physical page address (PPA, Physical Page Address) mapping table, solid-state hard disk in The operating system is registered as a block device and formatted as a fixed file system. The file system manages the mapping relationship between files and logical addresses (LBA, LogicalBlock Address). When accessing data, the file system issues LBA, and FTL converts LBA into LPA, then converts LPA into PPA, and finally finds user data. In this method, operations such as device registration and formatting of the solid-state hard disk in the system are firstly performed, and there...
