Embodiment in application, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, the range of the application protection is belonged to.
With the continuous development of memory technology, storing equipment becomes essential life and work use in people's daily life
Product.And be a kind of based non-volatile random access medium using flash memory NAND Flash as the solid-state hard disk SSD of storage medium,
Have the characteristics that data do not disappear, capacity is big, read or write speed is fast and suitable mass data storage after power-off, even more gradually at
Form is stored for mainstream.Compared to performance the leaping of having had matter next of the hard disk drive of conventional magnetic media.
The storage equipment of the application includes USB flash drive (USB flash disk), SD card (secure data card, Secure
Digital Memory Card), SSD (solid state hard disk, Solid State Drives), EMMC (embedded storage card,
Embedded Multi Media Card) and EMCP (embedded multi-die package, embedded Multi Chip
Package), CF card (Compact Flash) and other servers and processor etc. with storage equipment.
Under the premise of guaranteeing memory space, accelerate writing speed, present embodiment proposes following method for writing data,
As shown in Figure 1.Fig. 1 is the application method for writing data, is included the following steps:
S101: the writing commands of data to be written are received.
Store equipment when not carrying out reading and writing data or after completing reading and writing data, do not receive new write instruction it
Before, it can be in idle condition.In the idle state, storage equipment executes idle task, and in the implementation procedure of idle task
In, new writing commands are judged whether there is at predetermined time intervals.
Wherein, which is generally several milliseconds, can also adjust the predetermined time according to different demands.
If receiving new writing commands, data to be written are obtained from the writing commands.
Wherein, above-mentioned idle task includes data transfer, further includes carrying out idle scan to storage equipment, clearing and retrieving is write
Enter the operation tasks such as the rubbish that data to be written generate.
When storage equipment is in idle condition, when host host issues the writing commands of data to be written, it is desirable that storage
When data are written in equipment, correspondingly, storage equipment receives the writing commands.The writing commands include data to be written length,
The logical address of data to be written, the write-in type of data to be written such as random address are written.
S102: judge whether the first mode of the storage equipment is opened.
The first mode is no write de-lay mode, i.e. SLC (single layer cell, Single-Level Cell) write mode, the
One mode Writing condition is no write de-lay condition.
Since the writing speed of no write de-lay mode is substantially better than other write modes, the storage of present embodiment
Equipment first determines whether first mode i.e. no write de-lay mode opens after the write instruction for receiving data to be written.
S103: if the first mode is opened, receiving data to be written, is written using the first mode described to be written
Enter data；Conversely, then judging whether the data to be written are setting write-in type.
If the first mode for storing equipment is opened, data to be written are received, and directly adopt the i.e. fast literary sketch of first mode
Enter mode and the data to be written are written.If the first mode of storage equipment is not opened, storage equipment further judges to be written
Enter whether data are setting write-in type.
Wherein, this sets write-in type and is written as random address.
S104: if the data to be written are setting write-in type, the data to be written are written using first mode；
Conversely, the data to be written then are written using second mode.
Specifically, in solid state hard disk reading data or writing process, the speed of random address write-in is that measurement solid-state is hard
One important indicator of disk processing capacity, and the number per second being written and read, i.e. IOPS performance are to measure storage equipment
One Xiang Zhibiao of random address writing speed.IOPS index is higher under normal conditions, illustrates the data processing energy of solid-state hard disk SSD
Power is stronger.IOPS performance is thus improved, can be improved random address writing speed.And use first mode, that is, no write de-lay mode
Above-mentioned data to be written are written, can be improved the number of write operation per second to improve IOPS index, further increase storage equipment
Writing speed.Therefore, it if the write-in type of data to be written is that random address is written, directlys adopt no write de-lay mode and writes
Enter data to be written.
If first mode is not opened, and the write-in type of data to be written is the write-in of nonrandom address, then uses second
The data to be written are written in mode.
Wherein, the second mode be MLC (multilevel-cell, Multi-Level Cell) write mode, TLC (three-layer unit,
Trinary-Level Cell) any one of write mode or QLC (four layer units, Quad-Level Cell) write mode.
In the above method, by first judging whether no write de-lay mode opens, data write mode is determined, it can be not
The writing speed for accelerating data under the premise of storage equipment amount of storage is influenced, the burst write performance of storage equipment is improved, and
Facilitating transplanting, practicability is wide, and the storage equipment of the storage performance of low performance can be made to obtain preferable burst write performance index,
Improve user experience.
In another embodiment, as shown in Fig. 2, Fig. 2 is the process of the second embodiment of the application wiring method
Schematic diagram.Storage equipment is in idle condition, and before the write instruction for receiving data to be written, storage sets first standby judge whether completely
Sufficient first mode unlocking condition, i.e. no write de-lay mode unlocking condition.First mode is opened if meeting, opens above-mentioned the
One mode, if conditions are not met, then opening above-mentioned second mode.Specifically comprise the following steps:
S201: judging whether the storage equipment meets, and a) idle capacity of the storage equipment is greater than first threshold；Or
B) free time of the storage equipment is greater than second threshold, while the idle capacity is greater than the first threshold.
S202: if meet it is above-mentioned a) or b) when, open first mode.Conversely, opening second mode.
Wherein, which is no write de-lay mode, i.e. mould is written in SLC (single layer cell, Single-Level Cell)
Formula, first mode unlocking condition are no write de-lay unlocking condition.
The second mode be MLC (multilevel-cell, Multi-Level Cell) write mode, TLC (three-layer unit,
Trinary-Level Cell) any one of write mode or QLC (four layer units, Quad-Level Cell) write mode.
In conjunction with S201 and S202, specifically, since no write de-lay SLC write mode is to sacrifice memory space and exchange write-in for
Speed, in order to guarantee memory space and write-in space combine, and be non-fully written using SLC no write de-lay mode to
Data are written.Therefore, a first threshold is arranged to the idle capacity of storage equipment, for example, when memory space is 100G, by this
One threshold value is set as 70G.When idle capacity is greater than the first threshold, first mode is opened.It should if idle capacity is not more than
First threshold opens second mode.
In addition, can be carried out to the data of its inside since storage equipment is not when being in idle condition has reading and writing data
It arranges.Such as data transfer, garbage reclamation, idle scan, if processing idle task with by no write de-lay data simultaneously into
If row, the writing speed of data can be seriously affected.Therefore, in order to avoid temporal conflict in present embodiment, to the free time
The duration of time is limited.Second threshold is such as set as 1 minute or 30 seconds.If the free time of storage equipment is less than
Second threshold opens second mode.If the free time for storing equipment is greater than the second threshold, in order to guarantee no write de-lay
Exploitativeness, need to further judge store equipment idle capacity whether be greater than first threshold, if idle capacity be greater than this first
Threshold value then opens first mode.If free time be greater than the second threshold, and idle capacity be not more than first threshold when, open
Open second mode.
S203: the writing commands of data to be written are received.
When storage equipment is in idle condition, when host host issues the writing commands of data to be written, it is desirable that storage
When data are written in equipment, correspondingly, storage equipment receives the writing commands.The writing commands include the length of data to be written,
Type such as random address is written to be written.
S204: judge whether the first mode of the storage equipment is opened.
Since the writing speed of no write de-lay mode is substantially better than other write modes, the storage of present embodiment
Equipment first determines whether first mode i.e. no write de-lay mode opens after the write instruction for receiving data to be written.
If first mode is opened, S205 is executed.If first mode is not turned on, S206 is executed.
S205: the data to be written are written using the first mode.
Data to be written are received, data are written using no write de-lay mode, the speed that the data to be written are written can be accelerated
Rate effectively improves the write performance of storage equipment.
S206: judge whether the data to be written are setting write-in type.
Wherein, this sets write-in type and is written as random address.
Specifically, in solid state hard disk reading data or writing process, the speed of random address write-in is that measurement solid-state is hard
One important indicator of disk processing capacity, and the number per second being written and read, i.e. IOPS performance are to measure storage equipment
One Xiang Zhibiao of random address writing speed.IOPS index is higher under normal conditions, illustrates the data processing energy of solid-state hard disk SSD
Power is stronger.IOPS performance is thus improved, can be improved random address writing speed.And use first mode, that is, no write de-lay mode
Above-mentioned data to be written are written, can be improved the number of write operation per second to improve IOPS index, further increase storage equipment
Writing speed.Therefore, it if the write-in type of data to be written is that random address is written, directlys adopt no write de-lay mode and writes
Enter data to be written.
Type is written if it is setting, executes S205.If data to be written are not setting write-in types, S207 is executed.
S207: the data to be written are written using second mode.
In the above method, by first judging whether no write de-lay mode opens, data write mode is determined, it can be not
The writing speed for accelerating data under the premise of storage equipment amount of storage is influenced, the burst write performance of storage equipment is improved, and
Facilitate transplanting, practicability is wide, and the storage equipment of the storage performance of low end performance can be made to obtain preferable burst write performance and referred to
Mark improves user experience.
In any of the above-described embodiment, since data storage is a lasting dynamic process, and it is not limited to certain
One judgement.Such as storage equipment receives write instruction in idle state and passes through the second mould since first mode is not opened
Data to be written are written in formula, are not meant to that entire writing process requires to be written using second mode.Alternatively, due to fast literary sketch
Entering is to obtain writing speed with space to read, and first mode is opened and data to be written are written by first mode, is also not intended to
Entire writing process meet first mode Writing condition.Therefore, enter after host writes data mode in storage equipment, into one
Step ground persistently judges to store whether equipment meets first mode Writing condition.As shown in figure 3, Fig. 3 is the application data write-in side
The flow diagram of the third embodiment of method.Include the following steps:
S301: the writing commands of data to be written are received.
S302: judge whether the first mode of the storage equipment is opened.
S303: if the first mode is opened, receiving data to be written, is written using the first mode described to be written
Enter data；Conversely, then judging whether the data to be written are setting write-in type.
S304: it if the data to be written are setting write-in type, is written using the first mode described to be written
Data；Conversely, the data to be written then are written using second mode.
Wherein, S301~S304 is identical as S101~S104, please specifically participate in S101~S104 and its related text description,
Details are not described herein.
S305: judge whether the storage equipment meets first mode Writing condition.
Wherein, it is setting write-in type which, which is data to be written,；Or data to be written are non-set
Surely type is written, but the idle capacity for storing equipment is greater than first threshold；Or data to be written are that type is written in non-setting, but deposits
The free time for storing up equipment is greater than second threshold, while idle capacity is greater than first threshold.
Wherein, this sets write-in type and is written as random address.
Storage equipment first determines whether the write-in type of data to be written is random address write-in, the data symbols to be written
Close no write de-lay condition.Specifically, in solid state hard disk reading data or writing process, the speed of random address write-in is to measure
One important indicator of solid state hard disk processing capacity, and the number per second being written and read, i.e. IOPS performance are that measurement is deposited
Store up a Xiang Zhibiao of the performance of equipment random address write-in.IOPS index is higher under normal conditions, illustrates the number of solid-state hard disk SSD
It is stronger according to processing capacity.IOPS performance is thus improved, can be improved random address writing speed.And use first mode, that is, quick
Above-mentioned data to be written are written in write mode, can be improved the number of write operation per second to improve IOPS index, further increase
Store the writing speed of equipment.Therefore, if the write-in type of data to be written is that random address is written, the number to be written is determined
According to meeting no write de-lay condition.
If the write-in type of data to be written is that type, idle the holding of storage equipment judgement storage equipment is written in non-setting
Whether amount is greater than first threshold.If idle capacity is greater than first threshold, which is written item
Part, that is, no write de-lay condition.Specifically, since no write de-lay SLC write mode is to sacrifice memory space and exchange writing speed for
, in order to guarantee that memory space and write-in space combine, and non-fully write using first mode SLC no write de-lay mode
Enter data to be written.Therefore, a first threshold is arranged to the idle capacity of storage equipment, for example, when memory space is 100G, it will
The first threshold is set as 70G.When idle capacity is greater than the first threshold, above-mentioned data fit no write de-lay item to be written
Part.Such as idle capacity be greater than 70G when, meet no write de-lay condition.
If the write-in type of data to be written is that type is written in non-setting, judge whether the free time for storing equipment is big
In second threshold.If free time is greater than second threshold, judge whether the idle capacity is greater than first threshold.If storage
The idle capacity of equipment is greater than first threshold, then the data fit no write de-lay condition to be written.Specifically, due to storing equipment
When being in idle condition does not have reading and writing data, the data of its inside can be arranged, such as garbage reclamation, idle scan,
Freed data blocks will be written using second mode using the data reproduction of the data block of first mode write-in, after writing, erasing is adopted
With the data etc. for the data block that first mode is written, if processing idle task is simultaneously carried out with by no write de-lay data
Words, can seriously affect the writing speed of data.Therefore, in order to avoid temporal conflict in present embodiment, to free time
Duration limited.Second threshold is such as set as 1 minute or 30 seconds.If the free time for storing equipment be greater than this
Two threshold values need to further judge whether the idle capacity for storing equipment is greater than first to guarantee the exploitativeness of no write de-lay
Threshold value, if idle capacity is greater than the first threshold, the data fit no write de-lay condition to be written
If meeting first mode Writing condition, S306 is executed, if not meeting the first model Writing condition, is executed
S308。
S306: the data to be written are written using first mode.
S307: whether judgement currently still conforms to first mode Writing condition.
In writing process, whether still storage equipment further judge current first mode write-in unlocking condition, such as sentences
Whether the idle capacity of disconnected current storage devices is greater than first threshold.S306 is executed if meeting, if do not met, is executed
S308。
S308: data to be written are written using second mode.
S309: new writing commands are judged whether there is.
Equipment is stored after writing current data to be written, further determines whether to receive new writing commands, such as
Fruit receives new writing commands, executes step S302.If not receiving new writing commands, S310 is executed.
S310: entering idle state, executes idle task, and judge whether there is new writing commands.
Wherein, which includes data transfer, is specifically included the data for the data block being written using first mode,
Again freed data blocks are written using second mode；After the completion of write-in, the data for the data block that erasing is written using first mode.
Idle task further includes that idle scan is carried out to storage equipment, and clearing and retrieving is written the operations such as the rubbish that data to be written generate and appoints
Business.
Further, storage equipment judges whether idle task executes completion, if completion is not carried out, in idle task
In implementation procedure, new order write-in is judged whether there is at predetermined time intervals.
Wherein, which is generally several milliseconds, can also adjust the predetermined time according to different demands.
If the storage equipment receives new writing commands during executing idle task, S302 is executed.In circulation
State writing process.If not receiving new writing commands during executing idle task, S311 is executed.
S311: storage equipment enters dormant state.
Equipment is stored after entering dormant state, Host next time is waited to wake up.
It is different from the prior art, the storage equipment of present embodiment is sentenced first after idle state receives writing commands
Whether the no write de-lay mode of disconnected storage equipment opens, and no write de-lay mode data to be written is used if on, conversely, then
Data to be written are written using low-speed writing mode.By first judging whether no write de-lay mode opens, determine that mould is written in data
Formula can accelerate the writing speed of data under the premise of not influencing to store equipment amount of storage, improve the burst of storage equipment
Write performance, and facilitate transplanting, practicability is wide, and the storage equipment of the storage performance of low performance can be made to obtain preferable burst and write
Enter performance indicator, improves user experience.
In terms of hardware structure, present applicant proposes storage equipment, referring to Fig. 4, the storage equipment packet of present embodiment

Time is less than second threshold, opens second mode.It is fast in order to guarantee if the free time for storing equipment is greater than the second threshold
The exploitativeness that literary sketch enters, processor 42 need to further judge whether the idle capacity for storing equipment is greater than first threshold, if empty
Not busy capacity is greater than the first threshold, then opens first mode.If free time is greater than the second threshold, and idle capacity is little
When first threshold, second mode is opened.
In any of the above-described embodiment, since data storage is a lasting dynamic process, and it is not limited to certain
One judgement.Such as storage equipment receives write instruction in idle state and passes through the second mould since first mode is not opened
Data to be written are written in formula, are not meant to that entire writing process requires to be written using second mode.Alternatively, due to fast literary sketch
Entering is to obtain writing speed with space to read, and first mode is opened and data to be written are written by first mode, is also not intended to
Entire writing process meet first mode Writing condition.Therefore, enter processing after host writes data mode in storage equipment
Device 42 further persistently judges to store whether equipment meets first mode Writing condition.
It specifically includes processor 42 and judges whether the storage equipment meets first mode Writing condition.Wherein, this first
Mode Writing condition is that data to be written are setting write-in type；Or data to be written are that type is written in non-setting, but storage is set
Standby idle capacity is greater than first threshold；Or data to be written are that type is written in non-setting, but the free time for storing equipment is big
In second threshold, while idle capacity is greater than first threshold.Wherein, this sets write-in type and is written as random address.
If meeting first mode Writing condition, the data to be written are written using first mode in processor 42.If
The first model Writing condition is not met, data to be written are written using second mode in processor 42.And it is write meeting first mode
After entering condition, whether judgement currently still conforms to first mode Writing condition.If met, continue that institute is written using first mode
Data to be written are stated, anyway, remaining data is written using second mode.
Processor 42 further determines whether to receive new writing commands, such as after writing current data to be written
Fruit receives new writing commands, continues to execute and the step of whether first mode is opened judged.If not receiving new write-in
Order executes idle task into idle state, and judges whether there is new writing commands.
Wherein, which includes data transfer, is specifically included the data for the data block being written using first mode,
Again freed data blocks are written using second mode；After the completion of write-in, the data for the data block that erasing is written using first mode.
Idle task further includes that idle scan is carried out to storage equipment, and clearing and retrieving is written the operations such as the rubbish that data to be written generate and appoints
Business.
Further, processor 42 judges whether idle task executes completion, if completion is not carried out, in idle task
In implementation procedure, new order write-in is judged whether there is at predetermined time intervals.
Wherein, which is generally several milliseconds, can also adjust the predetermined time according to different demands.
If the processor 42 receives new writing commands during executing idle task, judgement first mode is executed
The process whether opened.If processor 42 does not receive new writing commands during executing idle task, storage equipment into
Enter dormant state.
Equipment is stored after entering dormant state, Host next time is waited to wake up.
It is different from the prior art, the processor 42 of present embodiment is sentenced first after idle state receives writing commands
Whether the no write de-lay mode of disconnected storage equipment opens, and no write de-lay mode data to be written is used if on, conversely, then
Data to be written are written using low-speed writing mode.By first judging whether no write de-lay mode opens, determine that mould is written in data
Formula can accelerate the writing speed of data under the premise of not influencing to store equipment amount of storage, improve the burst of storage equipment
Write performance, and facilitate transplanting, practicability is wide, and the storage equipment of the storage performance of low end performance can be made to obtain preferable burst
Write performance index improves user experience.
