Region；By the data storage to be stored to the target separate storage region.
For example, 4 available separate storage regions are a, b, c, d, and corresponding completed reading and writing data number of times respectively
Between 1500 to 2000 times, and corresponding memory space is followed successively by 100G, 90G, 95G and 10G respectively, it is seen then that although this 4
Individual separate storage region difference on completed reading and writing data number of times is smaller, but still has very big difference on memory space
, especially separate storage region d.So being can be while hard disk service life be improved, also with respect to the work for improving hard disk
Make efficiency, it is to avoid the data of memory space less separate storage region d storages are more and reduce the operating efficiency of hard disk, because
This, is when data storage is carried out, can preferentially by any one in data Cun Chudao a, b, c to be stored or multiple.
When determining at least one available independence according to the completed reading and writing data number of times of each separate storage region
After storage region, determine that target is independently deposited by further with the corresponding memory space of each available separate storage region
Storage area domain, can avoid the data of and storage smaller because of some separate storage region memory space more and have influence on whole hard
The operating efficiency of disk.
In an embodiment of the invention, for target separate storage region is determined more accurately out, can further include：
Determine that each block in each described available separate storage region distinguishes corresponding memory space；It is described according to each
The memory space of the individual available separate storage region, being determined from described at least one available separate storage region can
Target separate storage region, including：Using equation below (1), each available separate storage region is calculated
Memory space utilization rate；
Wherein, μiCharacterize the memory space utilization rate of available separate storage region described in i-th；mijCharacterize i-th institute
State the memory space of block described in j-th in available separate storage region；UiCharacterize and available independently deposited described in i-th
The memory space in storage area domain；kiCharacterize the quantity of the block in available separate storage region described in i-th；By minimum
The corresponding available separate storage region of the memory space utilization rate is defined as target separate storage region.
For example, with define 3 available separate storage area e, f, g and respectively corresponding memory space 100G, 95G,
As a example by 90G, then when determining target separate storage region in e, f, g, be determined using formula (1).Below with the 1st
10 are included in separate storage region e altogether9As a example by individual block, in e is determined 109Block distinguishes corresponding memory spaceAfterwards, the memory space utilization rate of separate storage region e can be calculated by data above (specific calculating process is not given), in addition, it is assumed that separate storage
The corresponding memory space utilization rate of region f and g is respectively μ2=50%, μ3=60%, it is not difficult to draw μ1＜ μ2＜ μ3, therefore, can
Preferentially by data storage to be stored to e.
In addition, if the μ for calculating1、μ2And μ3Between difference be almost 0, then data to be stored can also be put down
Share and store in this 3 separate storage regions.
When determining at least one available independence according to the completed reading and writing data number of times of each separate storage region
After storage region, by further calculating the memory space utilization rate of each available separate storage region, and minimum is selected
The corresponding separate storage region of memory space utilization rate carry out data storage, more accurate, reliable can improve hard disk
Operating efficiency.
In an embodiment of the invention, in order to ensure the completed number of each separate storage region for determining each time
According to read-write number of times accuracy, it is described by the data storage to be stored to the target separate storage region after, enter one
Step includes：The corresponding completed reading and writing data number of times of the target separate storage region in the statistical table is added 1.
For example, the completed reading and writing data number of times that target separate storage region is the e of storage in e, and statistical table is
1500 times, then, it is necessary to be updated to the data in statistical table, i.e. 1500+1 after by data Cun Chudao e to be stored
=1501, then when data storage is carried out next time, the corresponding completed reading and writing datas of e in the statistical table for inquiring
Number of times will be 1501.
And for example, data to be stored are respectively stored into n (>=2) individual separate storage region, then after storage is completed, should
The corresponding completed reading and writing data number of times of this n separate storage region in statistical table is added 1.
After a data storage is completed, read by by the completed data of corresponding separate storage region in statistical table
Write number of times and plus 1, can effectively ensure that the accuracy of the completed reading and writing data number of times of storage, and then can more accurately make
The read-write of data is evenly distributed on DISK to Image, for the service life for improving hard disk lays the foundation.
In an embodiment of the invention, the specific implementation step of the step 104 may include：By the data to be stored
Store to available separate storage region each described.
For example, with determine 4 available separate storage area a, c, e, f, respectively corresponding residual memory space as 20G,
10G, 25G, 15G and size of data to be stored are for as a example by 30G, then can be according to each available separate storage region 4
Residual memory space percentage in individual available separate storage region is stored, and e.g., the residual memory space percentage of a isSimilarly, it may be determined that go out c, e, f to distinguish corresponding residual memory space percentage is λ2
=14.3%, λ3=35.7%, λ4=21.4%, such that it is able to determine size of data to be stored in a, c, e, f, such as a respectively
Size of data to be stored is 28.6%*30G=8.58G, and other can similarly be obtained.
And for example, when the size of data to be stored is respectively less than 4 available separate storage area a, c, e, the f for determining, may be used also
Data to be stored are stored in this 4 separate storage regions according to 25% ratio uniform.
A kind of date storage method provided in an embodiment of the present invention will be described in detail below, as shown in Fig. 2 the party
Method may comprise steps of：
Step 201：N (>=2) individual separate storage region is created on SSD in advance.
For example, can be by running NVMECLI create-ns orders under corresponding operating system, when the control in SSD
After chip gets the order, the control chip just can according in the order carry corresponding information (e.g., the quantity of establishment and
The memory space of each separate storage region to be created) N (>=2) individual separate storage region is created that, wherein, 2≤N≤16.
Step 202：Pre-set statistical table.
Separate storage region and the completed column information of reading and writing data number of times two should be corresponded in the statistical table.
Step 203：N number of separate storage region is stored using statistical table distinguish corresponding completed reading and writing data
Number.
For example, creating the common N=5 separate storage region of a, b, c, d and e in above-mentioned steps 201, then can just lead to
Cross in the statistical table of setting in step 202. and store a, b, c, d and e and distinguish corresponding completed reading and writing data number of times,
Such as, respectively 8000 times, 3000 times, 2000 times, 7000 times and 2500 times.
What deserves to be explained is, the storage form of the completed reading and writing data number of times of separate storage region is not limited to this hair
Statistical table in bright embodiment, can also be other diversified forms, such as blank document.
Step 204：Reception carries the data storage request of data to be stored.
Step 205：Query statistic form, and determine that N number of separate storage region difference is corresponding in statistical table
The reading and writing data number of times of completion.
By taking a, b, c, d and e in step 203 as an example.
Step 206：In N number of completed reading and writing data number of times, n (>=1) is selected individual relatively minimal completed

Between magnitude relationship be a ＞ d ＞ b ＞ e ＞ c, and the wherein corresponding completed reading and writing data number of times of b, c, e is relatively minimal, and
The corresponding completed reading and writing data number of times relative maximum of a, d.
Step 207：It is determined that the n relatively minimal corresponding separate storage area of completed reading and writing data number of times selected
Domain is available separate storage region.
Because the corresponding completed reading and writing data number of times of b, c, e is relatively minimal, it is possible to by this 3 separate storage areas
Domain is defined as available separate storage region, and avoids that data Cun Chudao to be stored currently has been carried out into excessive secondary data read-write
A, d in.
Step 208：It is determined that the n memory space of available separate storage region selected.
For example, the corresponding memory space of b, c, e is respectively 200G, 50G and 80G.
Step 209：It is determined that each block in the n available separate storage region selected distinguishes corresponding storage
Space.
For example, including 2*10 in b105*10 is included in individual block, c98*10 is included in individual block and e9Individual block, wherein,
Because the quantity of block is more, therefore each block in available separate storage region b, c and e uses space m1j(j
From 1 to 2*1010)、m2j(j is from 1 to 5*109) and m3j(j is from 1 to 8*109) the present is indicated.
Step 210：Calculate the n memory space utilization rate μ of available separate storage regioni(1≤i≤n)。
By taking b as an example, using formula (1)Calculate memory space utilization rate
Similarly, the memory space utilization rate μ of c and e2And μ3Also can be drawn by formula, specific calculating process is similar to, and number of times is repeated no more,
Such as, there is μ2=65%, μ3=45%.
Step 211：In n μiIn, by minimum μx(1≤x≤n) corresponding available separate storage region is defined as mesh
Mark separate storage region.
Then had by step 210, μ2＞ μ1＞ μ3, therefore, μ3Corresponding available separate storage region e is independently deposited for target
Storage area domain.
Step 212：By data storage to be stored to target separate storage region.
In this step, can be by data storage to be stored to e.
Step 213：The corresponding completed reading and writing data number of times of target separate storage region in statistical table is added 1.
After this storage is completed, the completed reading and writing data number of times 2500+1 of the e that will should be stored in statistical table
=2501, therefore, when data storage is carried out again next time, the completed data of the e got by query statistic form
Read-write number of times is 2501 times.
