Technique effect.
Technical solution of the present invention is described in detail below by attached drawing and specific embodiment, it should be understood that the application
Specific features in embodiment and embodiment are the detailed description to technical scheme, rather than to present techniques
The restriction of scheme, in the absence of conflict, the technical characteristic in the embodiment of the present application and embodiment can be combined with each other.
The terms "and/or", only a kind of incidence relation of description affiliated partner, indicates that there may be three kinds of passes
System, for example, A and/or B, can indicate：Individualism A exists simultaneously A and B, these three situations of individualism B.In addition, herein
Middle character "/", it is a kind of relationship of "or" to typically represent forward-backward correlation object.
In order to which become apparent from that open the embodiment of the present application provided a kind of is grouped according to bad block distribution dynamic time raid
Some terms are described below in method and apparatus.
Solid state disk (Solid State Drives) referred to as consolidates disk, and solid state disk (Solid State Drive) is with admittedly
State electronic store chip array and manufactured hard disk, are made of control unit and storage unit (FLASH chip, dram chip).
Solid state disk is identical with common hard disc in the specification and definition, function and application method of interface, in product design and
It is also completely consistent with common hard disc in size.It is widely used in military, vehicle-mounted, industry control, video monitoring, network monitoring, network
The fields such as terminal, electric power, medical treatment, aviation, navigation equipment.
Die is divided into die, plane, block inside NAND chip, and page, die are the blockage on wafer, a chip
In may encapsulate several die, a chip includes N number of die
Raid, disk array (Redundant Arrays of Independent Disks, RAID), there is " independent disk
The meaning of the array with redundant ability constituted ".
Embodiment one
Fig. 1 is that a kind of flow of method according to bad block distribution dynamic time raid groupings in the embodiment of the present invention is illustrated
Figure.As shown in Figure 1, the method includes：
Step 110：Obtain the bad block in the first Die in SSD hard disks, wherein there is N number of Die, institute in the SSD hard disks
Stating SSD hard disks has the Raid of group N+1；
Specifically, the SSD hard disks, that is, solid state disk, in solid state disk life cycle, the life of the solid state disk
In other words it is exactly the time for capableing of normal use in the solid state disk that the life period, which refers to the service life of the solid state disk,
It is interior, it can normally read and write, the SSD hard disks have the Raid of group n+1, and the Raid is exactly disk array (Redundant
Arrays of Independent Disks, RAID), there is the meaning of " array with redundant ability that independent disk is constituted ".Magnetic
Disk array is to be combined into the huge disk group of a capacity by the relatively inexpensive disk of many prices, and number is provided using individual disks
According to the entire disk system efficiency of produced addition effect promoting.Using this technology, data are cut into many sections, are deposited respectively
It is placed on each hard disk.
Step 120：Judge the idle block number in the first Die；
Step 130：When the idle block number is less than predetermined threshold, it sets the first Die to read-only status；
Further, the method further includes：After setting the first Die to read-only status, idle good block is replaced
For the bad block.
Specifically, in step 120, step 130, the idle number of blocks in the first Die, the sky are first determined whether
Not busy block refers to just memory block that is not being written and read and being normally carried out read-write operation, obtains the predetermined of the free block
Threshold value, the predetermined threshold can be according to actual conditions come sets itself, and the application is not intended to be limited in any this, need to illustrate
It is the idle block number judged in the first Die；With obtain predetermined threshold in no particular order sequence, can obtain, also may be used simultaneously
Successively obtain.When the idle block number is less than predetermined threshold, that is to say, that when there is bad block, if free block is sufficient
It is more than enough, then replace bad block using good block.When the available free blocks of the first Die disappear, this Die enters read-only shape
State, rather than entire hard disk enters read-only status, and, the feelings that can not be written excessive in some Die bad block thus may be implemented
Under condition, which, which remains unchanged, can be written the technique effect of data.
Step 140：Continue to read and write using remaining N-1 Die；
Step 150：When residue when the last one Die that can be read and write, the SSD hard disks are set as read-only totally；
If the first Die is the Die for storing verification data, Raid is re-started.
Specifically, after some Die enters read-only status, Raid is carried out using remaining Die automatically, if
This Die is the Die for storing verification data, then needs to carry out Raid again.
Further, the method further includes：When continuing read-write using remaining N-1 Die, the SSD is hard
Disk has the Raid of group (N-2)+1.
Specifically, continuing the Raid of read-write group (n-2)+1 using remaining n-1 Die, when residue, the last one can
Totally read-only, the solid-state disk service life termination to be carried out when the Die of read-write, can using method provided by the embodiments of the present application
It can continue to remaining most latter two Die always with the data of write-in.
