如：数据通信链路建立状态良好，则控制器10控制固态存储设备100两侧的指示灯70全部显示绿色。
可以理解的是，若数据通信链路建立状态良好，则控制器10控制固态存储设备100任意一侧的指示灯70全部显示绿色。
如果数据通信链路建立成功，则控制器10控制固态存储设备100两侧的指示灯70显示绿色；如：固态存储设备100两侧的指示灯70分别有三个LED或两个LED灯显示为绿色。
若数据通信链路未建立成功，则控制器10控制固态存储设备100两侧的指示灯70全部不显示绿色。
可以理解的是，若数据通信链路建立成功，则控制器10控制固态存储设备100两侧的指示灯70分别有至少两个LED灯同时显示为绿色。或任意一侧的指示灯70至少有两个LED灯显示为绿色。
可以理解的是，固态存储设备100两侧的指示灯70显示为绿色的LED灯数量越多，表明数据通信链路连接状态越好。
请一并参阅图7，图7为本发明实施例提供的一种固态存储设备的信息备份状态示意图。
当数据通信链路建立成功后，控制器10会发送请求备份指令给用户终端200，请求备份指令为是否同意备份，若用户终端200同意备份，则固态存储设备100通过无载波通信天线40接收数据，并将数据传输至固态存储设备100中的flash存储器或上位机进行存储，则控制器10会控制指示灯70显示备份状态。
若固态存储设备100两侧的指示灯的颜色同时由绿色变为蓝色，则固态存储设备100正在进行数据备份。或如固态存储设备100任意一侧的指示灯由绿色变为蓝色，则为数据备份状态。
可以理解的是，指示灯70中LED灯显示蓝色的数量可以表示数据备份的进度，如：固态存储设备100每侧的指示灯中包含四个LED灯，则每一个LED灯变为蓝色，代表数据传输了25％，若有三个LED灯变为蓝色，则数据传输了75％；若四个LED灯全部变为蓝色，则表明数 据传输完毕。
请一并参阅图8，图8为本发明实施例提供的一种固态存储设备的数据传输中断状态示意图。
当用户终端200在数据传输进行中离开固态存储设备100时，固态存储设备100与用户终端200之间的通信连接会中断，此时，控制器10会控制指示灯70全部显示为红色，持续一段时间后，指示灯70熄灭，当固态存储设备100两侧的指示灯70全部显示为红色时，数据传输中止。
在其他实施例中，若固态存储设备任意一侧的指示灯70全部显示红色时，则数据传输中止。
如：当手机正在向固态存储设备100传输数据时，手机突然离开固态存储设备100，此时，手机与固态存储设备100之间的数据通信链路中断，固态存储设备100两侧的指示灯70全部显示为红色，持续10s左右后，指示灯70熄灭，数据传输中止。
若将用户终端200重新放在固态存储设备100上时，固态存储设备100与用户终端200重新建立数据通信链路，固态存储设备100会继续上次备份中未完成的部分。
可以理解的是，当固态存储设备100与用户终端200重新建立数据通信链路后，控制器10控制flash存储器20接收与flash存储器不同的数据，其中，与flash存储器不同的数据指flash存储器中不存在的数据，也即，用户终端200的数据未备份至flash存储器中。
请一并参阅图9，图9为本发明实施例提供的一种固态存储设备的低电量状态示意图。
如果固态存储设备100处于低电量状态，则控制器10会控制固态存储设备100两侧的指示灯70分别有一个LED灯同时显示为红色，其中，低电量状态是指不能满足固态存储设备100工作所需的电量，如：当固态存储设备100中的电量低于10％时，可设置为低电量状态。
当固态存储设备100处于低电量状态时，固态存储设备100两侧的指示灯70分别有一个LED灯显示为红色，用户观察的指示灯70的一个LED灯显示为红色时，需要对固态存储设备100进行充电。
可以理解的是，当固态存储设备100任意一侧的指示灯70其中一个LED灯显示为红色时，则该固态存储设备100处于低电量状态。
可以理解的是，用户可通过通用接口60接外部充电器对固态存储设备100进行充电；当充电一段时间后，固态存储设备100内的电量增加至大于10％的电量时，指示灯70会由红色显示为绿色，当指示灯70由红色全部变为绿色时，表明固态存储设备100的电量已经充满，可将通用接口60脱离外部充电器。
通过固态存储设备100两侧指示灯70的显示情况可判断固态存储 设备100的工作状态，便于用户直观的掌握固态存储设备100的存储状态，方便根据指示灯70的显示情况调整固态存储设备100的工作状态。
本发明实施例提供了一种固态存储设备，通过将用户终端200放置固态存储设备100上，控制器10控制无载波通信芯片30与用户终端200建立点对点数据通信链路，控制器10控制无载波通信芯片30接收用户终端200的数据并存储在存储器20中，从而解决了目前数据传输时需要通过第三方软件组网建立无线通信链接，操作过程比较繁琐，并且传输效率不稳定的技术问题，从而，提高了数据传输的效率。
请一并参阅图10，图10为本发明实施例提供的一种数据传输方法的流程示意图；该数据传输方法应用于固态存储设备，其中，固态存储设备可以具体为U盘、SSD、eMMC、eMCP、UFS及SD卡等设备，存储设备可具体由存储控制器和存储介质组成，存储控制器的功能可具体由控制芯片实现，存储介质的功能可具体由存储芯片实现，存储芯片为flash芯片，flash类型的芯片可具体为NAND flash芯片等。如图10所述，该方法包括：
110、与用户终端建立点对点数据通信链路。
上述“用户终端”为待备份的电子产品，其中，该电子产品可以为手机，平板电脑和录音机等。
上述“点对点数据通信”为网内任意两个用户之间的信息交换，点对点的通信时，只有一个用户可收到信息。如：当用户终端A与固态存储器建立点对点通信链路后，其他的用户终端不可以再与固态存储器建立点对点通信链路，即，当用户终端A向固态存储器传输数据时，其他用户终端不能通过该数据通信链路再向固态存储设备传输数据。
在本实施例中，当用户终端置于固态存储设备上时，固态存储设备的无载波通信天线接收来至于用户终端的信号，并将该信号发送至无载波通信芯片，无载波通信芯片接收并处理该信号，无载波通信芯片将处理后的信号发送至控制器，控制器控制无载波通信芯片与用户终端建立点对点数据通信链路。
120、通过所述数据通信链路发送数据传输请求。
上述“数据传输请求”为请求数据备份的指令或请求数据传输的指令，其中，上述数据备份指令为是否同意数据备份，上述请求数据传输的指令为是否同意接收数据。
所述数据传输请求具体包括：备份用户终端数据请求或发送固态存储设备数据请求，其中，“备份用户终端数据请求”指控制器控制固态存储设备向用户终端发送数据备份请求，上述“发送固态存储设备数据请求”指控制器控制固态存储设备向用户终端发送数据请求。
若用户终端为手机，下面以手机为例进行举例说明。
当手机向固态存储设备传输数据进行备份时，将手机放置在固态存 储设备上，控制器控制手机与固态存储设备建立点对点通信链路，控制器控制固态存储设备向手机发送数据备份请求，此时，手机接收到固态存储设备发送的数据备份请求后，手机显示屏会显示“是”和“否”的指令，若用户选择“是”，则表示同意将手机内的数据备份至固态存储设备，若用户选择“否”则表示不同意将手机内的数据备份至固态存储设备。
可以理解的是，若用户超过预设时间后，仍然没有选择“是”或“否”，则表明用户放弃将手机内的数据备份至固态存储设备，其中，预设时间可以根据实际情况进行设定，例如，预设时间可以为30s或60s。
可以理解的是，若用户选择同意将手机内的数据备份至固态存储设备，在备份过程中，发现传输错误，可以选择手机上的“返回”指令，“返回”指令表明用户放弃正在备份的数据。
当固态存储设备向手机发送数据时，将手机放置在固态存储设备上，控制器控制手机与固态存储设备建立点对点数据通信链路，控制器控制固态存储设备向手机发送数据请求，其中，该数据请求为是否接收固态存储设备内的数据，此时手机接收到该数据请求后，手机显示屏会出现“是”或“否”的指令，若用户选择“是”，表示同意接收固态存储设备内的数据，若用户选择“否”，表示不同意接收固态存储设备内的数据。
可以理解的是，若用户超过预设时间后，仍然没有选择“是”或“否”，则表明用户放弃接收固态存储设备内的数据，其中，预设时间可以根据实际情况进行设定，例如，预设时间可以为30s或60s。
可以理解的是，若用户同意接收固态存储设备内的数据，在传输过程中，发现传输错误，可以选择手机上的“返回”指令，“返回”指令表明用户放弃接收正在传输的数据。
130、根据所述数据传输请求的确认响应，进行数据传输。
所述根据所述数据传输请求的确认响应，进行数据传输，包括：根据所述备份用户终端数据请求的确认响应，将所述用户终端数据备份至所述固态存储设备，或者根据所述发送固态存储设备数据请求的确认响应，将所述固态存储设备数据发送至所述用户终端。
上述“确认响应”具体为固态存储设备接收到来自用户终端的确认反馈，控制器则控制固态存储设备接收用户终端传输的数据以备份至固态存储设备，或者控制固态存储设备向用户终端传输数据。
当点对点数据通信链路断开后，重新建立点对点通信链路后，所述数据传输方法还包括：固态存储设备向用户终端发送已备份的数据，接收用户终端未备份的数据。
上述“固态存储设备向用户终端发送已备份的数据”为点对点数据通信链路断开前已经传输至固态存储设备中的内容，固态存储设备会对已经备份的数据进行标记，重新建立点对点数据通信链路后，将标记的数据反馈至用户终端，用户终端接收到该反馈后，可以只传输未备份的数 据，该方法可以有效节省备份时间，提高数据备份的效率。
本发明实施例提供一种数据传输的方法，该方法通过将用户终端与固态存储设备建立点对点数据通信链路，通过所述数据通信链路发送数据传输请求，根据所述数据传输请求的确认响应，进行数据传输，解决了目前数据传输时需要通过第三方软件组网建立无线通信链接，操作过程比较繁琐，并且传输效率不稳定的技术问题，同时提高了数据传输的效率。
