Abstract
The invention discloses a kind of method for lifting solid state hard disc write performance, it is characterised in that slc cache size is dynamically adjusted according to the size of overall valid data amount dynamic；When totally idle, most of idle mlc/tlc block are converted into slc block；When overall valid data amount is smaller, the idle mlc/tlc block in part are converted into slc block；When overall valid data amount is larger, and when having been over slc cache maximum amount of data, slc block will be gradually reduced, part slc block are reverted into mlc/tlc block.Pass through the dynamic slc block switching modes based on overall valid data amount (Total Valid Page Count), valid data amount is actually written into according to actual user, to adjust slc block quantity, use of the solid state hard disc to slc block can be effectively improved.
Description
Technical field
The present invention relates to solid state hard disc control technology, the method for more particularly to lifting solid state hard disc write performance.
Background technology
Solid storage device with slc cache be exactly in the solid state hard disc of mlc/tlc types in order to lift writing rate,
Part mlc/tlc is marked off into partial-partition and is converted to slc, as data buffer storage, due to slc compared to mlc/tlc with more
Excellent write performance, essence are exactly to pass through space for time.In existing band slc cache solid storage device, slc cache
Size it is related with slc block quantity；Because mlc/tlc block switch to slc block to cause block capacity
Reduce, increase slc block quantity by switching more mlc/tlc block, the reduction of physical capacity, institute can be caused
With in general band slc cache solid state hard discs, slc block negligible amounts and it is relative be it is fixed, can not maximum limit
The characteristic using slc of degree.Fig. 1 is the stream compression figure using static slc cache modes；When slc cache have vacant,
Host data writes slc cache, when slc cache data write full, in host data write-in mlc.Because mlc block are cut
Being changed to slc block can cause capacity to reduce, therefore slc cache size is smaller.
The content of the invention
For disadvantages described above, the present invention seeks to how the significantly more efficient use for improving solid state hard disc to slc block,
Realize the purpose for improving solid state hard disc write performance.
A kind of method for lifting solid state hard disc write performance is proposed in order to solve the problem above present invention, it is characterised in that dynamic
State adjusts slc cache size according to the size dynamic of overall valid data amount；, will be most of idle when totally idle
Mlc/tlc block are converted to slc block；When overall valid data amount is smaller, the idle mlc/tlc block in part are turned
It is changed to slc block；, will be by when overall valid data amount is larger, and when having been over slc cache maximum amount of data
Decrescence small slc block, part slc block are reverted into mlc/tlc block.
The method of described lifting solid state hard disc write performance, it is characterised in that be dynamically determined slc block according to the following rules
Quantity n；n<(MN-CH)/(M-m)；Overall valid data amount (TotalValidPageCount) is C, and slc block are single
Capacity be m, mlc/tlc block single capacity is M, and total block numbers are N, wherein slc block quantity totally
For n, because physical capacity have to be larger than actual valid data amount, it is assumed that physics minimum value must be the H of valid data capacity
Times, wherein H ＞ 1.
The present invention passes through the dynamic slc based on overall valid data amount (Total Valid Page Count)
Block switching modes, valid data amount is actually written into according to actual user, can be effective to adjust slc block quantity
Improve use of the solid state hard disc to slc block.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The present embodiment according to overall valid data amount (Total Valid Page Count) by dynamically entering Mobile state
Adjustment slc size.
Overall valid data amount record totally in whole mapping table and effectively count by effective data weight, the records of values
According to total amount, when electric in whole system, travel through whole mapping table and initialize the numerical value.The numerical value updates with the operation of system,
Record effective mapping total amount in current mapping table.
Fig. 2 is whole idle dynamic slc cache schematic diagrams of circling or whirl in the air, and is described under dynamic slc cache modes totally
Idle state, now overall valid data amount (Total Valid Page Count) is 0, and by most of mlc block
Be converted to slc block.
Dynamic slc cache schematic diagrams when Fig. 3 is with low volume data, when host data writes, write first
In slc cache, when overall valid data amount (Total Valid Page Count) is smaller, by existing slc
Cache can meet storage host data, therefore slc block need not be switched to mlc block.
Fig. 4 is dynamic slc cache schematic diagrams when valid data are more, in overall valid data amount (Total
Valid Page Count) it is larger when, slc cache maximum amount of data is had been over, now by moving slc
Block data-moving is converted to mlc block to increase memory space into mlcblock, while by slc block
Storage host data.By with upper type, ensure that less in overall valid data amount (Total Valid Page Count)
When, the performance of the solid storage device can accomplish pure slc particulates' properties, as overall valid data amount (Total Valid
Page Count) it is larger when, and can enough provides enough memory spaces to store the data.
Slc block quantity can pass through with the relation of overall valid data amount (Total Valid Page Count)
Equation below obtains.Assuming that overall valid data amount (Total Valid Page Count) is C, appearance single slc block
To measure as m, mlc/tlc block single capacity is M, and total block numbers are N totally, and wherein slc block quantity is n,
Because physical capacity have to be larger than actual valid data amount, it is assumed that physics minimum value must be H times of valid data capacity, can
It is as follows with C relation to obtain n：n<(MN-CH)/(M-m)；
After grain type and the solid state hard disc composition given in above-mentioned formula, M, N, m are fixed value, and H is the same as the disk
Design write amplification etc. correlation, be traditionally arranged to be the fixed value more than 1.Therefore what can be apparent from obtains the slc block of maximum
Quantity.
The above disclosed interest field for being only an embodiment of the present invention, sheet can not being limited with this certainly,
One of ordinary skill in the art will appreciate that all or part of flow of above-described embodiment is realized, and according to the claims in the present invention institute
The equivalent variations of work, still fall within the scope that the present invention is covered.
