A Solid State Disk (SSD) is a hard disk composed of a control unit and a solid state storage unit. The SSD has the same specification, function, and usage method of an interface as a general hard disk (i.e., a mechanical hard disk), and has a faster read/write speed and higher stability because the SSD does not have a mechanical rotation device of the general hard disk, and is widely used as a storage device of electronic devices (e.g., computers) in various fields.
When the electronic device uses the SSD as the storage device, both system data and non-system data are usually stored in the SSD. However, the conventional SSD generally stores the system data and the non-system data of the electronic device in a mixed manner, that is, the storage unit in the SSD is used for storing both the system data and the non-system data of the electronic device, which causes a large delay in the reading and writing operations of the system data. In addition, most of the storage units in the existing SSD adopt flash memory blocks with a three-level cell (TLC) structure, and since the data read-write speed of the flash memory blocks with the TLC structure is slow, the read-write operation of system data has a long time delay.
In addition, the read-write operation of the system data by the electronic device is generally a fragmentation operation with random addresses and small data length, so that extra filling data can be generated by adopting a flash memory block with a TLC structure in a storage unit, the write amplification of the SSD is increased, and the service life of the SSD is shortened.
In order to solve the foregoing technical problem, an embodiment of the present application first provides a solid state disk. Fig. 1 is a schematic structural diagram of a solid state disk according to an embodiment of the present application. As shown in fig. 1, the solid state disk 10 may include: a data manipulation device 11 and a plurality of storage units 12 connected to the data manipulation device 11.
The data operation device 11 may be a control unit. The data operation device 11 is used for performing data operations on the memory unit 12, for example, performing data writing operations (i.e., writing data into the memory unit 12) or data reading operations (i.e., reading data from the memory unit 12) on the memory unit 12.
The storage unit 12 is a physical (i.e., not logical) storage medium, and may be a flash memory (flash memory) block. For example, the memory unit 12 may be a flash block of a NAND (not AND, NAND) type, OR a flash block of a NOR (not OR, NOR) type, AND the specific type of the flash block is not particularly limited herein.
In the embodiment of the present application, the storage units 12 in the solid state disk 10 are divided into two types, each type includes at least one storage unit 12, and the two types of storage units 12 are defined through a first namespace and a second namespace, that is, the first namespace and the second namespace both correspond to at least one storage unit 12.
It should be noted that the storage unit 12 corresponding to the first namespace and the storage unit 12 corresponding to the second namespace are physically independent from each other, that is, the storage unit 12 corresponding to the first namespace is different from the storage unit 12 corresponding to the second namespace, that is, the storage unit 12 corresponding to the first namespace is not overlapped with the storage unit 12 corresponding to the second namespace.
And the first name space and the second name space are both provided with one identifier. For example, the identification of the first namespace can be a first identification and the identification of the second namespace can be a second identification. In a specific application, the first identifier and the second identifier may both be composed of numbers, letters, or words, for example, the first identifier may be Namespace1, and the second identifier may be Namespace2.
In the embodiment of the present application, when the solid state disk 10 is used as a storage device of an electronic device (e.g., a mobile phone, a tablet computer, a notebook computer, or the like), the storage unit 12 corresponding to the first namespace may be used to store system data of the electronic device, and the storage unit 12 corresponding to the second namespace may be used to store non-system data of the electronic device. The system data may be data related to system operation of the electronic device, among other things. The system operation may be an operation related to an Operating System (OS) of the electronic device, for example, an installation operation of the OS or an installation operation of an Application (APP), or the like. The non-system data may be other data than the system data of the electronic device, such as audio data or video data, etc.
Since the electronic device has a high requirement on the time delay of the operation of the system data, that is, the operation of the system data is required to have a small time delay, in an embodiment of the present application, all the storage units 12 corresponding to the first namespace may be configured as a Single Level Cell (SLC) structure. Because the data read-write speed of the storage unit with the SLC structure is high, the data volume stored in each unit is small, and the service life of each unit is long, the storage unit with the SLC structure can reduce the time delay of the operation of system data, can reduce the write-in amplification of the SSD, and prolongs the service life of the SSD.
In another embodiment of the present application, the storage unit 12 corresponding to the second namespace may be configured as an SLC structure, or a multi-level cell (MLC) structure, or a TLC structure, or a quad-level cell (QLC) structure, and the like, which is specifically set according to actual requirements, and is not particularly limited herein.
Since the solid state disk 10 needs to communicate with the electronic device when serving as a storage device of the electronic device, please continue to refer to fig. 1, the solid state disk 10 may further include an interface unit 13.
Illustratively, the interface unit 13 may include: a high-speed serial computer extended bus (PCIE) interface, a Serial Advanced Technology Attachment (SATA) interface, a Serial Attached SCSI (SAS) interface, or a Mini SATA (MSATA) interface, etc. SCSI refers to Small Computer System Interface (Small Computer System Interface), among others.
In specific applications, when the electronic device needs to perform data operation on the solid state disk 10, a user may insert the solid state disk 10 into a corresponding interface slot on the electronic device, so that the solid state disk 10 establishes communication connection with the electronic device through the interface unit 13, and the electronic device further implements the data operation on the solid state disk 10.
Based on the solid state disk provided by the embodiment, the embodiment of the application further provides a data operation method of the solid state disk. Fig. 2 is a flowchart of an implementation of a data operation method of a solid state disk provided in an embodiment of the present application, and as shown in fig. 2, the data operation method may include S21 to S23, which are detailed as follows:
s21: the electronic equipment acquires the configuration information of the solid state disk.
In the embodiment of the application, after the electronic device establishes communication connection with the solid state disk, the electronic device needs to acquire configuration information of the solid state disk, where the configuration information is used to describe a configuration situation of a storage unit in the solid state disk. Specifically, the configuration case may include the following: the storage unit of the solid state disk is defined by a first naming space and a second naming space; the storage unit corresponding to the first namespace is used for storing system data of the electronic equipment, and the storage unit corresponding to the second namespace is used for storing non-system data of the electronic equipment; the identifier of the first namespace is a first identifier and the identifier of the second namespace is a second identifier.
In a possible implementation manner, after the electronic device establishes a communication connection with the solid state disk, the electronic device may actively acquire configuration information of the solid state disk. In this implementation, the electronic device may send a configuration information acquisition request to the solid state disk. After receiving the configuration information acquisition request, the solid state disk may return the configuration information of the solid state disk to the electronic device in response to the configuration information acquisition request.
In another possible implementation manner, after the electronic device establishes a communication connection with the solid state disk, the electronic device may passively receive configuration information of the solid state disk sent by the solid state disk. In this implementation manner, after the electronic device establishes communication connection with the solid state disk, the solid state disk may actively send configuration information of the solid state disk to the electronic device. The electronic equipment receives the configuration information of the solid state disk sent by the solid state disk.
S22: and the electronic equipment generates a data operation instruction based on the configuration information and the information of the data to be operated, and sends the data operation instruction to the solid state disk.
In the embodiment of the application, after the electronic device acquires the configuration information of the solid state disk, data operation can be performed on the solid state disk. The data operations may include: a data read operation or a data write operation, etc.
When the electronic device needs to perform data operation on the solid state disk, the electronic device may generate a data operation instruction based on the configuration information of the solid state disk and the information of the data to be operated, and send the data operation instruction to the solid state disk. The information of the data to be operated may include: data type, identification, content, etc. For example, the data types of the data to be operated on may include: system data or non-system data. The identifier of the data to be operated may be a name of the data to be operated, or may be a name of a file in which the data to be operated is located, or the like.
In one embodiment of the present application, the electronic device may generate the data operation instruction by:
determining the identifier of a target namespace corresponding to a storage unit to which the data to be operated belongs based on the data type of the data to be operated;
and generating the data operation instruction based on the identification of the target namespace and the identification or the content of the data to be operated.
In a possible implementation manner of this embodiment, when the data type of the data to be operated is system data, the electronic device determines that the storage unit to which the data to be operated belongs is a storage unit used for storing the system data in the solid state disk, that is, a storage unit corresponding to the first namespace, and therefore, the electronic device determines that the target namespace is the first namespace. Based on the data operation instruction, the electronic equipment generates a data operation instruction based on the first identifier of the first namespace and the identifier or the content of the data to be operated.
In another possible implementation manner of this embodiment, when the data type of the data to be operated is non-system data, the electronic device determines that the storage unit to which the data to be operated belongs is a storage unit used for storing the non-system data in the solid state disk, that is, a storage unit corresponding to the second namespace, and therefore, the electronic device determines that the target namespace is the second namespace. Based on the operation command, the electronic equipment generates a data operation command based on the second identifier of the second namespace and the identifier or the content of the data to be operated.
Therefore, in the embodiment of the application, the data operation instruction generated by the electronic device carries information of the data to be operated and the identifier of the target namespace corresponding to the storage unit to which the data to be operated belongs.
In this embodiment, the electronic device generates the data operation instruction based on the identifier of the target namespace and the identifier or the content of the data to be operated, which may specifically include the following two cases:
in case 1, the electronic device needs to perform data reading operation on the solid state disk.
In this case, the electronic device may generate the data reading instruction based on the identifier of the target namespace and the identifier of the data to be read. Specifically, if the data to be read is system data of the electronic device, the electronic device may generate a data reading instruction based on a first identifier of the first namespace and an identifier of the data to be read; if the data to be read is non-system data of the electronic device, the electronic device may generate a data reading instruction based on the second identifier of the second namespace and the identifier of the data to be read. That is, the data reading instruction generated by the electronic device includes an identifier of data to be read and an identifier of the target namespace.
And in case 2, the electronic equipment needs to perform data writing operation on the solid state disk.
In this case, the electronic device may generate the data write instruction based on the identification of the target namespace and the content of the data to be written. Specifically, if the data to be written is system data of the electronic device, the electronic device may generate a data writing instruction based on the first identifier of the first namespace and the content of the data to be written; if the data to be written is non-system data of the electronic device, the electronic device may generate a data writing instruction based on the second identifier of the second namespace and the content of the data to be written. That is, the data writing instruction generated by the electronic device includes the content of the data to be written and the identifier of the target namespace.
S23: the solid state disk receives a data operation instruction from the electronic equipment.
In the embodiment of the application, after the solid state disk receives the data operation instruction sent by the electronic device, the data operation instruction can be analyzed to obtain the identifier of the target namespace corresponding to the storage unit to which the data to be operated belongs and the information of the data to be operated.
In an embodiment of the present application, if the solid state disk detects that the identifier of the target namespace is the first identifier, the solid state disk executes S24. In another embodiment of the present application, if the solid state disk detects that the identifier of the target namespace is the second identifier, the solid state disk executes S25.
S24: and if the solid state disk detects that the identifier of the target name space is the first identifier, performing data operation on the storage unit corresponding to the first name space based on the information of the data to be operated.
In this embodiment, when the identifier of the target namespace carried in the data operation instruction is the first identifier, it is described that the data to be operated is system data of the electronic device, and at this time, the solid state disk may perform data operation on the storage unit corresponding to the first namespace based on the information of the data to be operated carried in the data operation instruction.
Specifically, when the data operation instruction is a data reading instruction, the solid state disk may read the data to be read from the storage unit corresponding to the first namespace based on the identifier of the data to be read carried in the data reading instruction. When the data operation instruction is a data writing instruction, the solid state disk can write the content of the data to be written carried in the data writing instruction into the storage unit corresponding to the first namespace.
S25: and if the solid state disk detects that the identifier of the target name space is the second identifier, performing data operation on a storage unit corresponding to the second name space based on the information of the data to be operated.
In this embodiment, when the identifier of the target namespace carried in the data operation instruction is the second identifier, it is indicated that the data to be operated is non-system data of the electronic device, and at this time, the solid state disk may perform data operation on the storage unit corresponding to the second namespace based on the information of the data to be operated carried in the data operation instruction.
Specifically, when the data operation instruction is a data reading instruction, the solid state disk may read the data to be read from the storage unit corresponding to the second namespace based on the identifier of the data to be read carried in the data reading instruction. When the data operation instruction is a data writing instruction, the solid state disk can write the content of the data to be written carried in the data writing instruction into the storage unit corresponding to the second namespace.
S24 and S25 are two parallel steps, and for a single data operation command, if the solid state disk executes S24, S25 is not executed, and if the solid state disk executes S25, S24 is not executed.
As can be seen from the above, in the data operation method of the solid state disk provided in this embodiment, since the storage units in the solid state disk are distinguished by the first namespace and the second namespace, that is, the storage unit corresponding to the first namespace is used for storing system data of the electronic device, and the storage unit corresponding to the second namespace is used for storing non-system data of the electronic device, when the electronic device needs to operate the system data, the electronic device only needs to carry the first identifier of the first namespace corresponding to the storage unit to which the system data belongs in the data operation instruction, and the solid state disk can perform data operation on the storage unit corresponding to the first namespace based on the data operation instruction; when the electronic device needs to operate the non-system data, the electronic device only needs to carry a second identifier of a second namespace corresponding to a storage unit to which the non-system data belongs in a data operation instruction, and the solid state disk can perform data operation on the storage unit corresponding to the second namespace based on the data operation instruction. The solid state disk respectively stores the system data and the non-system data of the electronic equipment in different storage units, so that the operation of the system data and the operation of the non-system data are not influenced mutually, and the time delay of the operation of the system data can be reduced.
Referring to fig. 3, fig. 3 is a schematic flowchart of a data operation method of a solid state disk according to another embodiment of the present application.
