Description
本申请要求于2021年10月08日在中国专利局提交的、申请号为202111172637.5的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本申请涉及数据存储技术领域，尤其涉及一种固态硬盘及其数据操作方法、装置及电子设备。
固态硬盘（solid state disk，SSD）是由控制单元和固态存储单元组成的硬盘。SSD在接口的规范、功能及使用方法上与普通硬盘（即机械硬盘）相同，由于SSD没有普通硬盘的机械旋转装置，因此具有更快的读写速度和更高的稳定性，被广泛用作各领域电子设备（例如，电脑）的存储装置。
电子设备采用SSD作为存储装置时，通常会将系统数据和非系统数据均存储在SSD中。然而，现有的SSD通常是将电子设备的系统数据和非系统数据进行混合存储，这样会导致系统数据的读写操作具有较大的时延。
有鉴于此，本申请实施例提供了一种固态硬盘及其数据操作方法、装置及电子设备，以解决现有的SSD的数据存储方式会导致系统数据的读写操作具有较大的时延的技术问题。

第二数据操作单元，用于若所述目标命名空间的标识为第二标识，则基于所述待操作数据的信息对第二命名空间对应的存储单元进行数据操作，所述第二命名空间对应的存储单元用于存储所述电子设备的非系统数据。
本申请实施例的第四方面提供了一种电子设备，包括：
第二通信单元，用于获取固态硬盘的配置信息，所述配置信息用于描述所述固态硬盘中的存储单元的配置情况；

实施本申请实施例提供的一种固态硬盘的数据操作方法、装置、固态硬盘、电子设备、计算机可读存储介质及计算机程序产品具有以下有益效果：
本申请实施例提供的一种固态硬盘的数据操作方法，由于通过第一命名空间和第二命名空间对固体硬盘中的存储单元进行区分，即第一命名空间对应的存储单元用于存储电子设备的系统数据，第二命名空间对应的存储单元用于存储电子设备的非系统数据，因此，当电子设备需要对系统数据进行操作时，电子设备只需将系统数据所属的存储单元对应的第一命名空间的第一标识携带在数据操作指令中，固态硬盘便可基于该数据操作指令对第一命名空间对应的存储单元进行数据操作；当电子设备需要对非系统数据进行操作时，电子设备只需将非系统数据所属的存储单元对应的第二命名空间的第二标识携带在数据操作指令中，固态硬盘便可基于该数据操作指令对第二命名空间对应的存储单元进行数据操作。即固态硬盘将电子设备的系统数据和非系统数据分别存储在不同的存储单元中，这样使得系统数据的操作与非系统数据的操作之间互不影响，从而可以降低系统数据的操作的时延。
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

固态硬盘（solid state disk，SSD）是由控制单元和固态存储单元组成的硬盘。SSD在接口的规范、功能及使用方法上与普通硬盘（即机械硬盘）相同，由于SSD没有普通硬盘的机械旋转装置，因此具有更快的读写速度和更高的稳定性，被广泛用作各领域电子设备（例如，电脑）的存储装置。
电子设备采用SSD作为存储装置时，通常会将系统数据和非系统数据均存储在SSD中。然而，现有的SSD通常是将电子设备的系统数据和非系统数据进行混合存储，即SSD中的存储单元既用来存储电子设备的系统数据，又用来存储电子设备的非系统数据，这样会导致系统数据的读写操作具有较大的时延。且现有的SSD中的存储单元大多采用的是三层单元（triple level cell，TLC）结构的闪存块，由于TLC结构的闪存块的数据读写速度较慢，因此也会导致系统数据的读写操作具有较大的时延。
此外，电子设备对系统数据的读写操作一般是地址随机、数据长度较小的碎片化操作，因此存储单元采用TLC结构的闪存块会产生额外的填充数据，增大SSD的写入放大，从而缩短SSD的使用寿命。
为了解决上述技术问题，本申请实施例首先提供一种固态硬盘。图1为本申请实施例提供的一种固态硬盘的结构示意图。如图1所示，该固态硬盘10可以包括：数据操作装置11以及与数据操作装置11连接的多个存储单元12。
其中，数据操作装置11具体可以是控制单元。数据操作装置11用于对存储单元12进行数据操作，例如，对存储单元12进行数据写入操作（即，将数据写入存储单元12中）或者数据读取操作（即，从存储单元12中读取数据）。
存储单元12为物理上（即，非逻辑上）的存储介质，其具体可以是闪存（flash
memory）块（block）。示例性的，存储单元12可以是与非（not AND，NAND）类型的闪存块，也可以是或非（not OR，NOR）类型的闪存块，此处不对闪存块的具体类型做特别限定。
本申请实施例将固态硬盘10中的存储单元12分为两类，每类均包括至少一个存储单元12，且通过第一命名空间和第二命名空间分别定义这两类存储单元12，即第一命名空间和第二命名空间均对应至少一个存储单元12。
需要说明的是，第一命名空间对应的存储单元12和第二命名空间对应的存储单元12物理上相互独立，即第一命名空间对应的存储单元12不同于第二命名空间对应的存储单元12，也就是说，第一命名空间对应的存储单元12与第二命名空间对应的存储单元12不重叠。
其中，第一命名空间和第二命名空间均配置有一个标识。示例性的，第一命名空间的标识可以为第一标识，第二命名空间的标识可以为第二标识。在具体应用中，第一标识和第二标识均可以由数字、字母或文字等组成，例如，第一标识可以为Namespace1，第二标识可以为Namespace2。
本申请实施例中，当固态硬盘10被用作电子设备（例如，手机、平板电脑或笔记本电脑等）的存储装置时，第一命名空间对应的存储单元12可以用于存储电子设备的系统数据，第二命名空间对应的存储单元12可以用于存储电子设备的非系统数据。其中，系统数据可以是与电子设备的系统操作相关的数据。系统操作可以是涉及电子设备的操作系统（operating system，OS）的操作，例如，OS的安装操作或应用程序（application，APP）的安装操作等。非系统数据可以是除电子设备的系统数据之外的其它数据，例如音频数据或视频数据等。
由于电子设备对系统数据的操作的时延性要求较高，即要求系统数据的操作具有较小的时延，因此，在本申请的一个实施例中，第一命名空间对应的所有存储单元12均可以被配置为单层单元（single
level cell，SLC）结构。由于SLC结构的存储单元的数据读写速度较快，每个单元存储的数据量较小，且寿命较长，因此采用SLC结构的存储单元不仅可以降低系统数据的操作的时延，而且会缩小SSD的写入放大，增长SSD的使用寿命。
在本申请的另一个实施例中，第二命名空间对应的存储单元12可以被配置为SLC结构，或者多层单元（multi level cell，MLC）结构，或者TLC结构，或者四层单元（quad level cell，QLC）结构等，具体根据实际需求设置，此处不对其做特别限定。
由于固态硬盘10作为电子设备的存储装置时需要与电子设备进行通信，因此，请继续参阅图1，固态硬盘10还可以包括接口单元13。
示例性的，接口单元13可以包括：高速串行计算机扩展总线标准（peripheral
component interconnect express，PCIE）接口、串行高级技术附件（serial advanced technology attachment，SATA）接口、串行SCSI（serial attached SCSI，SAS）接口或迷你SATA（miniSATA，MSATA）接口等。其中，SCSI指小型计算机系统接口（Small Computer System Interface）。
在具体应用中，电子设备需要对固态硬盘10进行数据操作时，用户可以将固态硬盘10插入电子设备上相应的接口插槽中，使固态硬盘10通过接口单元13与电子设备建立通信连接，进而使电子设备实现对固态硬盘10的数据操作。
基于上述实施例提供的固态硬盘，本申请实施例还提供一种固态硬盘的数据操作方法。图2为本申请实施例提供的一种固态硬盘的数据操作方法的实现流程图，如图2所示，该数据操作方法可以包括S21~S23，详述如下：
S21：电子设备获取固态硬盘的配置信息。
本申请实施例中，电子设备与固态硬盘建立通信连接后，电子设备需要获取固态硬盘的配置信息，该配置信息用于描述固态硬盘中的存储单元的配置情况。具体地，该配置情况可以包括以下内容：固态硬盘的存储单元通过第一命名空间和第二命名空间定义；第一命名空间对应的存储单元用于存储电子设备的系统数据，第二命名空间对应的存储单元用于存储电子设备的非系统数据；第一命名空间的标识为第一标识，第二命名空间的标识为第二标识。
在一种可能的实现方式中，电子设备与固态硬盘建立通信连接后，电子设备可以主动获取固态硬盘的配置信息。该实现方式中，电子设备可以向固态硬盘发送配置信息获取请求。固态硬盘接收到该配置信息获取请求后，可以响应于该配置信息获取请求，向电子设备返回固态硬盘的配置信息。
在另一种可能的实现方式中，电子设备与固态硬盘建立通信连接后，电子设备可以被动接收固态硬盘发送的固态硬盘的配置信息。该实现方式中，电子设备与固态硬盘建立通信连接后，固态硬盘可以主动向电子设备发送固态硬盘的配置信息。电子设备接收固态硬盘发送的固态硬盘的配置信息。
S22：电子设备基于所述配置信息以及待操作数据的信息生成数据操作指令，并向固态硬盘发送所述数据操作指令。
本申请实施例中，电子设备获取到固态硬盘的配置信息后，可以对固态硬盘进行数据操作。数据操作可以包括：数据读取操作或数据写入操作等。
电子设备需要对固态硬盘进行数据操作时，电子设备可以基于固态硬盘的配置信息以及待操作数据的信息生成数据操作指令，并向固态硬盘发送该数据操作指令。其中，待操作数据的信息可以包括：数据类型、标识及内容等。示例性的，待操作数据的数据类型可以包括：系统数据或非系统数据。待操作数据的标识可以是待操作数据的名称，或者可以是待操作数据所在文件的名称等。
在本申请的一个实施例中，电子设备可以通过以下步骤生成数据操作指令：
基于所述待操作数据的数据类型确定所述待操作数据所属的存储单元对应的目标命名空间的标识；
基于所述目标命名空间的标识以及所述待操作数据的标识或内容，生成所述数据操作指令。
在本实施一种可能的实现方式中，当待操作数据的数据类型为系统数据时，电子设备确定待操作数据所属的存储单元为固态硬盘中用于存储系统数据的存储单元，即第一命名空间对应的存储单元，因此，电子设备确定目标命名空间为第一命名空间。基于此，电子设备基于第一命名空间的第一标识以及待操作数据的标识或内容，生成数据操作指令。
在本实施另一种可能的实现方式中，当待操作数据的数据类型为非系统数据时，电子设备确定待操作数据所属的存储单元为固态硬盘中用于存储非系统数据的存储单元，即第二命名空间对应的存储单元，因此，电子设备确定目标命名空间为第二命名空间。基于此，电子设备基于第二命名空间的第二标识以及待操作数据的标识或内容，生成数据操作指令。
由此可见，本申请实施例中，电子设备生成的数据操作指令中携带有待操作数据的信息以及待操作数据所属的存储单元对应的目标命名空间的标识。
本实施例中，电子设备基于目标命名空间的标识以及待操作数据的标识或内容，生成数据操作指令，具体可以包括以下两种情况：
情况1、电子设备需要对固态硬盘进行数据读取操作。
该情况下，电子设备可以基于目标命名空间的标识以及待读取数据的标识生成数据读取指令。具体地，若待读取数据为电子设备的系统数据，则电子设备可以基于第一命名空间的第一标识以及待读取数据的标识生成数据读取指令；若待读取数据为电子设备的非系统数据，则电子设备可以基于第二命名空间的第二标识以及待读取数据的标识生成数据读取指令。也就是说，电子设备生成的数据读取指令中包括待读取数据的标识以及目标命名空间的标识。
情况2、电子设备需要对固态硬盘进行数据写入操作。
该情况下，电子设备可以基于目标命名空间的标识以及待写入数据的内容生成数据写入指令。具体地，若待写入数据为电子设备的系统数据，则电子设备可以基于第一命名空间的第一标识以及待写入数据的内容生成数据写入指令；若待写入数据为电子设备的非系统数据，则电子设备可以基于第二命名空间的第二标识以及待写入数据的内容生成数据写入指令。也就是说，电子设备生成的数据写入指令中包括待写入数据的内容以及目标命名空间的标识。
S23：固态硬盘接收来自电子设备的数据操作指令。
本申请实施例中，固态硬盘接收到电子设备发送的数据操作指令后，可以对该数据操作指令进行解析，得到待操作数据所属的存储单元对应的目标命名空间的标识以及待操作数据的信息。
在本申请的一个实施例中，固态硬盘若检测到目标命名空间的标识为第一标识，则固态硬盘执行S24。在本申请的另一个实施例中，固态硬盘若检测到目标命名空间的标识为第二标识，则固态硬盘执行S25。
S24：固态硬盘若检测到所述目标命名空间的标识为第一标识，则基于所述待操作数据的信息对第一命名空间对应的存储单元进行数据操作。
本实施例中，当数据操作指令中携带的目标命名空间的标识为第一标识时，说明待操作数据为电子设备的系统数据，此时固态硬盘可以基于该数据操作指令中携带的待操作数据的信息，对第一命名空间对应的存储单元进行数据操作。
具体地，当数据操作指令为数据读取指令时，固态硬盘可以基于该数据读取指令中携带的待读取数据的标识，从第一命名空间对应的存储单元中读取待读取数据。当数据操作指令为数据写入指令时，固态硬盘可以将数据写入指令中携带的待写入数据的内容写入第一命名空间对应的存储单元中。
S25：固态硬盘若检测到所述目标命名空间的标识为第二标识，则基于所述待操作数据的信息对第二命名空间对应的存储单元进行数据操作。
本实施例中，当数据操作指令中携带的目标命名空间的标识为第二标识时，说明待操作数据为电子设备的非系统数据，此时固态硬盘可以基于数据操作指令中携带的待操作数据的信息，对第二命名空间对应的存储单元进行数据操作。
具体地，当数据操作指令为数据读取指令时，固态硬盘可以基于该数据读取指令中携带的待读取数据的标识，从第二命名空间对应的存储单元中读取待读取数据。当数据操作指令为数据写入指令时，固态硬盘可以将数据写入指令中携带的待写入数据的内容写入第二命名空间对应的存储单元中。
需要说明的是，S24和S25为两个并列步骤，对于单个数据操作指令而言，固态硬盘若执行了S24则不执行S25，固态硬盘若执行了S25则不执行S24。
以上可以看出，本实施例提供的一种固态硬盘的数据操作方法，由于通过第一命名空间和第二命名空间对固体硬盘中的存储单元进行区分，即第一命名空间对应的存储单元用于存储电子设备的系统数据，第二命名空间对应的存储单元用于存储电子设备的非系统数据，因此，当电子设备需要对系统数据进行操作时，电子设备只需将系统数据所属的存储单元对应的第一命名空间的第一标识携带在数据操作指令中，固态硬盘便可基于该数据操作指令对第一命名空间对应的存储单元进行数据操作；当电子设备需要对非系统数据进行操作时，电子设备只需将非系统数据所属的存储单元对应的第二命名空间的第二标识携带在数据操作指令中，固态硬盘便可基于该数据操作指令对第二命名空间对应的存储单元进行数据操作。即固态硬盘将电子设备的系统数据和非系统数据分别存储在不同的存储单元中，这样使得系统数据的操作与非系统数据的操作之间互不影响，从而可以降低系统数据的操作的时延。
请参阅图3，图3为本申请另一实施例提供的一种固态硬盘的数据操作方法的示意性流程图。如图3所示，相对于图3对应的实施例，本实施例中的S21具体可以包括S211~S212，详述如下：
S211：电子设备向固态硬盘发送配置信息获取请求。
S212：固态硬盘接收来自所述电子设备的配置信息获取请求，并响应于所述配置信息获取请求，向所述电子设备返回所述固态硬盘的配置信息。
本实施例中，电子设备与固态硬盘建立通信连接后，电子设备可以主动获取固态硬盘的配置信息，即，电子设备可以向固态硬盘发送配置信息获取请求。固态硬盘接收到该配置信息获取请求后，可以响应于该配置信息获取请求，向电子设备返回固态硬盘的配置信息。
以上可以看出，本实施例提供的固态硬盘的数据操作方法，固态硬盘在接收到来自电子设备的配置信息获取请求后才会向电子设备发送固态硬盘的配置信息，从而可以避免浪费固态硬盘的处理资源。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
