Embodiment Construction

[0052] 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.

[0053] see Figure 4 In the first embodiment of the present invention, a solid-state hard disk 100 is provided, including a logical address layer 10 and a physical address layer 20, and the solid-state hard disk 100 includes:

[0054] The virtual address layer 30 is arranged between the logical address layer 10 and the physical address layer 20 of the solid state disk 100;

[0055] The user data blocks of the logical address layer 10 are respectively mapped to the corresponding virtual address layer 30; the virtual address layer 30 then maps the user data blocks to the corresponding physical addre...

Abstract

The present invention provides a method for mapping a disk array of a solid hard disk as well as the solid hard disk, and is applicable to the technical field of solid memory. The method comprises the steps of: setting a virtual address layer between a logic address layer and a physical address layer of the solid hard disk; respectively mapping a user data block of the logic address layer onto a corresponding virtual address layer; and the virtual address layer respectively mapping the user data block onto a corresponding physical address layer. Therefore, according to the present invention, the independence of the solid hard disk on the additional transfer interface part is reduced, and the manufacturing cost of the hard disk is lowered.

Description

technical field [0001] The invention relates to the technical field of solid-state hard disk storage, in particular to a method for mapping a solid-state hard disk disk array and the solid-state hard disk. Background technique [0002] Solid State Disk (SolidStateDisk, IDEFLASHDISK) is a hard disk made of an array of solid-state electronic storage chips, consisting of a control unit and a storage unit (FLASH chip). The interface specifications and definitions, functions and usage methods of SSDs are exactly the same as those of ordinary hard disks, and the product shape and size are also completely consistent with ordinary hard disks. Widely used in military, vehicle, industrial control, video surveillance, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and other fields. [0003] see figure 1 , in an invention patent with a Chinese application number of 200710036050.5 and an invention title of "solid-state hard disk memory ca...
