[0038] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0039] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0040] First, some nouns or terms that appear in the description of the embodiments of the present application are subject to the following interpretations:

[0041] LBA (Logical Block Addressing): It is a common mechanism for describing the blocks where data is located on computer storage devices.

[0042] Example 1

[0043] Figure 1 A schematic diagram of the structure of an optional storage hard disk is shown. Figure 1 As shown, a storage hard disk includes: a platter, inner and outer tracks, sectors, and cylinders. A platter is a circular magnetic disk. A platter can have two surfaces, and both the front and back sides can be read and written ( Figure 1 Only one disk surface is used as an example); the inner and outer tracks are the circles of tracks on the disk, the inner tracks are closer to the center of the circle, and the outer tracks are farther away from the center of the circle; sectors are small areas on the disk tracks separated by numbers ( Figure 1 1, 4, 31, 34 in the disk). Since the size of the sector is fixed, the number of sectors on the outer track is greater and the number of sectors on the inner track is less. The cylinder is a hollow cylinder composed of the tracks at the same position on the disk ( Figure 1 dark part in the image).

[0044] The reading and writing of storage hard disks mainly rely on the movement of two places: the magnetic arm controls the movement of the magnetic head between the circumference and the center of the circle. The movement range is the radius of the disk surface. In this way, the appropriate track can be found; the disk rotates around the center of the circle to move the appropriate sector under the magnetic head; when the disk is empty, the traditional data writing order is from the outer track to the inner track. When the disk rotates at the same angle, the outer track rotates a larger area, so the writing speed of the outer track is faster than that of the inner track. Based on this feature, the outer track performance of the hard disk is better, and the inner track performance is worse.

[0045] Currently, in order to achieve lower costs, the capacity of storage hard drives is getting larger and larger. While the mechanical structure of the disk reading and writing itself remains unchanged, that is, the seek time and disk rotation speed remain unchanged, in random read and write scenarios, the addressing range is larger, resulting in a decrease in the number of read and write operations per second on a single TB.

[0046] In order to solve the above problems, the embodiment of the present application takes into account the different data storage performance in different track areas of the storage hard disk, divides the storage hard disk into multiple track areas from the outside to the inside according to the tracks, and stores the target data in the corresponding track area according to the thermal state of the target data to be written, thereby achieving the purpose of improving the data storage performance of the storage hard disk.

[0047] The present application provides a data storage system. Figure 2 As shown, the system includes: a file management system 21 and a storage hard disk 22, wherein:

[0048] The storage hard disk 22 includes at least a mechanical hard disk, which includes multiple track areas;

[0049] The file management system 21 can implement different data storage methods.

[0050] The functions of each module of the data storage system are described below in conjunction with a specific implementation process.

[0051] Since traditional file systems cannot specify the LBA location to be written by themselves, staff can only know the file semantic interface provided by the file system. Therefore, the file management system in the embodiment of the present application uses a self-developed file system, which can specify the file to be written to the inner LBA or outer LBA of the mechanical hard disk.

[0052] In some scenarios, the storage hard disk is only a mechanical hard disk. In this case, the self-developed file system will store the target data in different track areas of the mechanical hard disk according to the data popularity.

[0053] As an optional implementation, the target data to be stored can be obtained, and the target heat of the target data can be determined; the target track area corresponding to the target heat can be determined from multiple track areas of the target hard disk based on a preset mapping relationship, wherein, in the mapping relationship, the higher the data heat, the farther the corresponding track area is from the center of the disk; the storage space status of the target track area can be determined, and the target storage strategy can be determined based on the storage space status, wherein the target storage strategy includes: storing the target data in the target track area, or storing the target data in an alternative track area corresponding to the target track area; and storing the target data according to the target storage strategy.

[0054] Optionally, all tracks of the mechanical hard disk are divided into a target number of track areas from far to near from the center of the disk based on a preset ratio; data temperature is divided from hot to cold into: a target number of temperature levels corresponding to the target number of track areas from far to near from the center of the disk.

[0055] Among them, the preset ratio and target number can be set according to actual needs. For example, 10% of the tracks from the outside to the inside are divided into the outer track area, 60% are divided into the middle track area, and 30% are divided into the inner track area. The data heat level can be divided into high heat, medium heat and low heat. In the mapping relationship, high heat corresponds to the outer track area, medium heat corresponds to the middle track area, and low heat corresponds to the inner track area.

[0056] Optionally, the target heat of the target data can be determined in the following manner: the target heat of the target data is determined using a pre-trained heat prediction model, wherein the heat prediction model is trained using historical data as training samples and the heat of the historical data as sample labels, wherein the heat of the historical data can be determined by users labeling it themselves.

[0057] When storing data, in order to avoid the situation where the storage hard disk is full and cannot continue to store data, after obtaining the target data to be stored, the target capacity of the target data can be determined first, and the remaining storage capacity of the target hard disk can be determined; if the target capacity is greater than the remaining storage capacity, an alarm message is output, wherein the alarm message is used to prompt that the storage capacity of the target hard disk is full and data storage cannot continue; if the target capacity is not greater than the remaining storage capacity, the target track area corresponding to the target temperature is further determined.

[0058] Optionally, after determining the target track area, the storage space status of the target track area can be determined in the following manner, and the target storage strategy can be determined based on the storage space status: determine whether there is a free sub-area in the target track area; if there is a free sub-area in the target track area, determine the target storage strategy to store the target data in the target track area; if there is no free sub-area in the target track area, determine the alternative track area corresponding to the target track area, and determine the target storage strategy to store the target data in the alternative track area.

[0059] Since the track area is user-defined, the remaining capacity of each track area cannot be directly obtained. Therefore, a user-defined bitmap mark can be used to determine whether each track area is full.

[0060] Specifically, each track area in the target hard disk corresponds to a first bitmap mark, and the first bitmap mark is used to indicate whether there is a free sub-area in the track area; when determining whether there is a free sub-area in the target track area, the first bitmap mark corresponding to the target track area can be detected, and whether there is a free sub-area in the target track area can be determined based on the first bitmap mark.

[0061] Optionally, when there is no free sub-area in the target track area, the alternative track area corresponding to the target track area can be determined in the following manner: if the target heat of the target data is higher than the preset heat, starting from the target track area, the next track area with a free sub-area is detected in order from near to far from the center of the disk as the alternative track area; if there is still no free sub-area until the outermost track area is detected, starting from the target track area, the next track area with a free sub-area is detected in order from far to near from the center of the disk as the alternative track area; if the target heat of the target data is not higher than the preset heat, starting from the target track area, the next track area with a free sub-area is detected in order from far to near from the center of the disk as the alternative track area; if there is still no free sub-area until the innermost track area is detected, starting from the target track area, the next track area with a free sub-area is detected in order from near to far from the center of the disk as the alternative track area.

[0062] It can be understood that if the target data is hot, a track area with free sub-areas that is closer to the target track area is selected from the outer track as the alternative track area; if the target data is hot, a track area with free sub-areas that is closer to the target track area is selected from the inner track as the alternative track area.

[0063] Taking the track area as an example, if the data heat is high and higher than the preset heat, the target track area is the outer track area, and its corresponding alternative track areas are: middle track area, inner track area; if the data heat is medium and higher than the preset heat, the target track area is the middle track area, and its corresponding alternative track areas are: outer track area, inner track area; if the data heat is medium and lower than the preset heat, the target track area is the middle track area, and its corresponding alternative track areas are: inner track area, outer track area; if the data heat is low and lower than the preset heat, the target track area is the inner track area, and its corresponding alternative track areas are: middle track area, outer track area.

[0064] Optionally, each track area in the target hard disk stores data with blocks as storage granularity, wherein each block includes a preset number of logical block addresses, and each logical block address corresponds to a sector of a preset size.

[0065] It can be understood that in the self-developed file system, the writing granularity is block, and the specific size of the block can be set according to actual needs. For example, 1 block is 1MB, and the sector represented by 1 logical block LBA is 4K, then 1 block has 256 sectors.

[0066] When storing the target data according to the target storage strategy, it can be done as follows: if the target storage strategy is to store the target data in the target track area, determine each free block in the target track area one by one, and write the target data into the free block until the target data storage is completed; when there are no free blocks in the target track area but the target data has not been stored completely, determine each free block in the alternative track area one by one, and continue to write the target data into the free block until the target data storage is completed; if the target storage strategy is to store the target data in the alternative track area, determine each free block in the alternative track area one by one, and write the target data into the free block until the target data storage is completed; when there are no free blocks in the alternative track area but the target data has not been stored completely, determine each free block in the next alternative track area corresponding to the alternative track area one by one, and continue to write the target data into the free block until the target data storage is completed.

[0067] Optionally, each block in each track area of ​​the target hard disk corresponds to a second bitmap flag, and the second bitmap flag is used to indicate whether the block is a free block. For example, the second bitmap flag can be represented by a bit value, taking a value of 0 or 1. When the bit value is 0, it indicates that no data has been written to the block, and when the bit value is 1, it indicates that data already exists in the block.

[0068] Optionally, a method for determining free blocks in a track area includes: starting from the starting position of the target area, detecting the second bitmap mark corresponding to each block one by one, and determining whether the detected block is a free block based on the second bitmap mark; wherein the target area includes one of the following: a target track area, an alternative track area, and the next alternative track area corresponding to the alternative track area.

[0069] It can be understood that the above solution is applicable to the case where the disk usage capacity of the storage hard disk is low. In this case, each block in the target storage area can be traversed, and as long as a block with no data written is detected, the corresponding target data can be stored in the corresponding block.

[0070] Taking into account the case where the disk usage capacity of the storage hard disk is high, if data is continued to be stored in the form of blocks traversing the target storage area as described above, it may take a lot of time and reduce storage efficiency. For example, there is a target data that is specified to be stored in the outer track area, but all the free sub-areas of the outer track area and the middle track area are not enough to store the complete target data. In this case, this storage needs to retrieve all the blocks in the outer track area and the middle track area. In the worst case, it may also be necessary to retrieve all the blocks in the inner track area. In this case, it is necessary to adopt another method to determine the free blocks in the track area.

[0071] Specifically, to improve the efficiency of free block retrieval, for each track area, each time data storage is completed, the target position of the last block of stored data in the track area may be recorded.

[0072] When determining the free blocks in the track area, you can start from the target position recorded when the target area was last stored with data, detect the second bitmap mark corresponding to each block one by one, and determine whether the detected block is a free block based on the second bitmap mark; if no free block is detected until the end of the target area, considering that some blocks before the target position may become free blocks due to data deletion, you can start again from the starting position of the target area, detect the second bitmap mark corresponding to each block one by one, and determine whether the detected block is a free block based on the second bitmap mark; wherein the target area includes one of the following: a target track area, an alternative track area, and a next alternative track area corresponding to the alternative track area.

[0073] Figure 3 A schematic diagram of determining free blocks is shown, such as Figure 3 As shown, starting from the third block of the target position recorded last time, the second bitmap mark of each block is determined in sequence. When the second bitmap mark of the fifth block is detected to be 0, it is determined that the fifth block is an available free block, and the target data can be written into the fifth block. After the writing is completed, the second bitmap mark of the fifth block is updated to 1; thereafter, there are no free blocks until the end of the target area, and the second bitmap mark of each block can be determined in sequence starting from the starting position of the target area, that is, the first block. When the second bitmap mark of the second block is detected to be 0, it is determined that the second block is an available free block, and the target data can be continued to be written into the second block. After the writing is completed, the second bitmap mark of the second block is updated to 1; thereafter, if the target data storage is completed, the process ends. If the target data storage is not completed, the above process is repeated in the next target area until the target data storage is completed.

[0074] In some scenarios, storage hard drives include both mechanical hard drives and solid-state drives. In this case, the self-developed file system can store the target data in different hard drives according to data popularity.

[0075] As an optional implementation, the target data to be stored can be obtained, and the target temperature of the target data can be determined; the target hard disk corresponding to the target temperature can be determined from multiple hard disks based on a preset mapping relationship; when the target hard disk is a solid-state hard disk, the target data is stored in the solid-state hard disk; when the target hard disk is a mechanical hard disk, the target track area corresponding to the target temperature can be determined from multiple track areas of the mechanical hard disk based on the mapping relationship, wherein, in the mapping relationship, the higher the temperature of the data, the farther the corresponding track area is from the center of the disk; the storage space status of the target track area is determined, and the target storage strategy is determined based on the storage space status, wherein the target storage strategy includes: storing the target data in the target track area, or storing the target data in the alternative track area corresponding to the target track area; storing the target data according to the target storage strategy.

[0076] Optionally, all tracks of the mechanical hard disk are divided into a target number of track areas from far to near from the center of the disk based on a preset ratio; data temperature is divided from hot to cold into: the highest temperature level corresponding to the solid-state hard disk, and a target number of temperature levels with a temperature lower than the highest temperature level corresponding to the target number of track areas from far to near from the center of the disk.

[0077] For example, from the outside to the inside, 10% of the mechanical hard disk tracks are divided into the outer track area, 60% are divided into the middle track area, and 30% are divided into the inner track area. The data heat level can be divided into ultra-high heat, high heat, medium heat and low heat. In the mapping relationship, ultra-high heat corresponds to the solid-state hard disk, high heat corresponds to the outer track area, medium heat corresponds to the middle track area, and low heat corresponds to the inner track area.

[0078] In some scenarios, users will also specify a storage location to store the target data. At this time, the self-developed file system can obtain the target data to be stored and obtain the specified track area of ​​the target data in the target hard disk, where the target hard disk includes multiple track areas; determine the storage space status of the specified track area, and determine the target storage strategy based on the storage space status, where the target storage strategy includes: storing the target data in the specified track area, or storing the target data in the alternative track area corresponding to the specified track area; storing the target data according to the target storage strategy.

[0079] In an embodiment of the present application, by dividing the target hard disk into multiple track areas and storing the target storage status, i.e., hot and cold data, in different track areas, the data storage performance of the target hard disk can be improved without increasing the cost in scenarios with high hot data concentration and large traffic, effectively solving the technical problem of the decrease in the throughput performance of the hard disk per unit time as the hard disk capacity increases.

[0080] Example 2

[0081] Based on the data storage system provided in Example 1, the embodiment of the present application also provides a data storage method. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0082] Figure 4 Flowchart of the data storage method according to the embodiment of the present application. Figure 4 As shown, the method may include the following steps:

[0083] Step S402: acquiring target data to be stored and determining the target popularity of the target data;

[0084] Step S404: determining a target track area corresponding to the target temperature from multiple track areas of the target hard disk according to a preset mapping relationship, wherein, in the mapping relationship, the higher the data temperature, the farther the corresponding track area is from the center of the disk;

[0085] Step S406: determining the storage space status of the target track area, and determining a target storage strategy based on the storage space status, wherein the target storage strategy includes: storing the target data in the target track area, or storing the target data in an alternative track area corresponding to the target track area;

[0086] Step S408: Store the target data according to the target storage policy.

[0087] The following describes each step of the data storage method in conjunction with a specific implementation process.

[0088] Optionally, the target hard disk is a mechanical hard disk, and all tracks of the mechanical hard disk are divided into a target number of track areas from far to near from the center of the disk based on a preset ratio; data heat is divided from hot to cold into: a target number of heat levels corresponding to the target number of track areas from far to near from the center of the disk.

[0089] Optionally, the target heat of the target data can be determined in the following manner: the target heat of the target data is determined using a pre-trained heat prediction model, wherein the heat prediction model is trained using historical data as training samples and the heat of the historical data as sample labels, wherein the heat of the historical data can be determined by users labeling it themselves.

[0090] When storing data, in order to avoid the situation where the storage hard disk is full and cannot continue to store data, after obtaining the target data to be stored, the target capacity of the target data can be determined first, and the remaining storage capacity of the target hard disk can be determined; if the target capacity is greater than the remaining storage capacity, an alarm message is output, wherein the alarm message is used to prompt that the storage capacity of the target hard disk is full and data storage cannot continue; if the target capacity is not greater than the remaining storage capacity, the target track area corresponding to the target temperature is further determined.

[0091] Optionally, after determining the target track area, the storage space status of the target track area can be determined in the following manner, and the target storage strategy can be determined based on the storage space status: determine whether there is a free sub-area in the target track area; if there is a free sub-area in the target track area, determine the target storage strategy to store the target data in the target track area; if there is no free sub-area in the target track area, determine the alternative track area corresponding to the target track area, and determine the target storage strategy to store the target data in the alternative track area.

[0092] Since the track area is user-defined, the remaining capacity of each track area cannot be directly obtained. Therefore, a user-defined bitmap mark can be used to determine whether each track area is full.

[0093] Specifically, each track area in the target hard disk corresponds to a first bitmap mark, and the first bitmap mark is used to indicate whether there is a free sub-area in the track area; when determining whether there is a free sub-area in the target track area, the first bitmap mark corresponding to the target track area can be detected, and whether there is a free sub-area in the target track area can be determined based on the first bitmap mark.

[0094] Optionally, when there is no free sub-area in the target track area, the alternative track area corresponding to the target track area can be determined in the following manner: if the target heat of the target data is higher than the preset heat, starting from the target track area, the next track area with a free sub-area is detected in order from near to far from the center of the disk as the alternative track area; if there is still no free sub-area until the outermost track area is detected, starting from the target track area, the next track area with a free sub-area is detected in order from far to near from the center of the disk as the alternative track area; if the target heat of the target data is not higher than the preset heat, starting from the target track area, the next track area with a free sub-area is detected in order from far to near from the center of the disk as the alternative track area; if there is still no free sub-area until the innermost track area is detected, starting from the target track area, the next track area with a free sub-area is detected in order from near to far from the center of the disk as the alternative track area.

[0095] It can be understood that if the target data is hot, a track area with free sub-areas that is closer to the target track area is selected from the outer track as the alternative track area; if the target data is hot, a track area with free sub-areas that is closer to the target track area is selected from the inner track as the alternative track area.

[0096] Optionally, each track area in the target hard disk stores data with blocks as storage granularity, wherein each block includes a preset number of logical block addresses, and each logical block address corresponds to a sector of a preset size.

[0097] When storing the target data according to the target storage strategy, it can be done as follows: if the target storage strategy is to store the target data in the target track area, determine each free block in the target track area one by one, and write the target data into the free block until the target data storage is completed; when there are no free blocks in the target track area but the target data has not been stored completely, determine each free block in the alternative track area one by one, and continue to write the target data into the free block until the target data storage is completed; if the target storage strategy is to store the target data in the alternative track area, determine each free block in the alternative track area one by one, and write the target data into the free block until the target data storage is completed; when there are no free blocks in the alternative track area but the target data has not been stored completely, determine each free block in the next alternative track area corresponding to the alternative track area one by one, and continue to write the target data into the free block until the target data storage is completed.

[0098] Optionally, each block in each track area in the target hard disk corresponds to a second bitmap mark, and the second bitmap mark is used to indicate whether the block is a free block.

[0099] On this basis, a method for determining the free blocks in the track area includes: starting from the starting position of the target area, detecting the second bitmap mark corresponding to each block one by one, and determining whether the detected block is a free block based on the second bitmap mark; wherein the target area includes one of the following: the target track area, the alternative track area, and the next alternative track area corresponding to the alternative track area.

[0100] It can be understood that the above solution is applicable to the case where the disk usage capacity of the storage hard disk is low. In this case, each block in the target storage area can be traversed, and as long as a block with no data written is detected, the corresponding target data can be stored in the corresponding block.

[0101] Taking into account the case where the disk usage capacity of the storage hard disk is high, if data is continued to be stored in the form of blocks traversing the target storage area as described above, it may take a lot of time and reduce storage efficiency. For example, there is a target data that is specified to be stored in the outer track area, but all the free sub-areas of the outer track area and the middle track area are not enough to store the complete target data. In this case, this storage needs to retrieve all the blocks in the outer track area and the middle track area. In the worst case, it may also be necessary to retrieve all the blocks in the inner track area. In this case, it is necessary to adopt another method to determine the free blocks in the track area.

[0102] Specifically, to improve the efficiency of free block retrieval, for each track area, each time data storage is completed, the target position of the last block of stored data in the track area may be recorded.

[0103] When determining the free blocks in the track area, you can start from the target position recorded when the target area was last stored with data, detect the second bitmap mark corresponding to each block one by one, and determine whether the detected block is a free block based on the second bitmap mark; if no free block is detected until the end of the target area, considering that some blocks before the target position may become free blocks due to data deletion, you can start again from the starting position of the target area, detect the second bitmap mark corresponding to each block one by one, and determine whether the detected block is a free block based on the second bitmap mark; wherein the target area includes one of the following: a target track area, an alternative track area, and a next alternative track area corresponding to the alternative track area.

[0104] In an embodiment of the present application, by dividing the target hard disk into multiple track areas and storing the target storage status, i.e., hot and cold data, in different track areas, the data storage performance of the target hard disk can be improved without increasing the cost in scenarios with high hot data concentration and large traffic, effectively solving the technical problem of the decrease in the throughput performance of the hard disk per unit time as the hard disk capacity increases.

[0105] Example 3

[0106] Based on the data storage system provided in Example 1, this embodiment of the application also provides a data storage method, such as Figure 5 As shown, the method may include the following steps:

[0107] Step S502: acquiring target data to be stored and determining the target popularity of the target data;

[0108] Step S504, determining a target hard disk corresponding to the target temperature from the multiple hard disks according to a preset mapping relationship;

[0109] Step S506, when the target hard disk is a solid state hard disk, storing the target data in the solid state hard disk;

[0110] Step S508, when the target hard disk is a mechanical hard disk, determine the target track area corresponding to the target temperature from multiple track areas of the mechanical hard disk based on the mapping relationship, wherein, in the mapping relationship, the higher the temperature of the data, the farther the corresponding track area is from the center of the disk; determine the storage space status of the target track area, and determine the target storage strategy based on the storage space status, wherein the target storage strategy includes: storing the target data in the target track area, or storing the target data in the alternative track area corresponding to the target track area; storing the target data according to the target storage strategy.

[0111] The following describes each step of the data storage method in conjunction with a specific implementation process.

[0112] Among them, all tracks of the mechanical hard disk are divided into a target number of track areas from far to near from the center of the disk based on a preset ratio; data temperature is divided from hot to cold into: the highest temperature level corresponding to the solid-state hard disk, and a target number of temperature levels with a temperature lower than the highest temperature level corresponding to the target number of track areas from far to near from the center of the disk.

[0113] For example, from the outside to the inside, 10% of the mechanical hard disk tracks are divided into the outer track area, 60% are divided into the middle track area, and 30% are divided into the inner track area. The data heat level can be divided into ultra-high heat, high heat, medium heat and low heat. In the mapping relationship, ultra-high heat corresponds to the solid-state hard disk, high heat corresponds to the outer track area, medium heat corresponds to the middle track area, and low heat corresponds to the inner track area.

[0114] When the target hard disk is a mechanical hard disk, the data storage method is the same as the process in Example 2. Since Example 2 has been described in detail, it will not be repeated here.

[0115] In an embodiment of the present application, by dividing the target hard disk into multiple track areas and storing the target storage status, i.e., hot and cold data, in different track areas, the data storage performance of the target hard disk can be improved without increasing the cost in scenarios with high hot data concentration and large traffic, effectively solving the technical problem of the decrease in the throughput performance of the hard disk per unit time as the hard disk capacity increases.

[0116] Example 4

[0117] Based on the data storage system provided in Example 1, this embodiment of the application also provides a data storage method, such as Figure 6 As shown, the method may include the following steps:

[0118] Step S602, obtaining target data to be stored, and obtaining a designated track area of ​​the target data in the target hard disk, wherein the target hard disk includes multiple track areas;

[0119] Step S604: determining the storage space status of the designated track area, and determining a target storage strategy based on the storage space status, wherein the target storage strategy includes: storing the target data in the designated track area, or storing the target data in an alternative track area corresponding to the designated track area;

[0120] Step S606: Store the target data according to the target storage policy.

[0121] Among them, the above scheme is mainly aimed at the scenario where the target hard disk is a mechanical hard disk. The process of determining the target storage strategy and storing the target data based on the storage space status of the specified track area can refer to the process of determining the target storage strategy and storing the target data based on the storage space status of the target track area in Example 2. Since Example 2 has been described in detail, it will not be repeated here.

[0122] It should be noted that this solution can also be extended to scenarios where the storage hard disks include both mechanical hard disks and solid-state hard disks. When the user specifies that the target hard disk is a solid-state hard disk, the target data can be directly stored in the solid-state hard disk.

[0123] In an embodiment of the present application, by dividing the target hard disk into multiple track areas and storing the target storage status, i.e., hot and cold data, in different track areas, the data storage performance of the target hard disk can be improved without increasing the cost in scenarios with high hot data concentration and large traffic, effectively solving the technical problem of the decrease in the throughput performance of the hard disk per unit time as the hard disk capacity increases.
