Windows获取电脑的硬盘属性(转速，类型(HDD,SSD))

获取电脑的硬盘属性(转速，类型(HDD,SSD))

参考的是老外技术论坛网站:https://stackoverflow.com/questions/23363115/detecting-ssd-in-windows

头文件.h

#pragma once
#include <QString>
#include <windows.h>
#include <string>//==============判断磁盘格式--获取到的是磁盘格式
void BuryPoint_GetDiskType(QStringList& disk_type);//==============判断硬盘类型()
//SpindleSpeed
//MediaType
//The Media Type gives you values:
//0 Unspecified
//3 HDD
//4 SSD
//5 SCM
void BuryPoint_GetDiskMediaType(QStringList& disk_media_type);class StorageDevice
{
public:StorageDevice() {};~StorageDevice() {};std::string  DeviceId;int BusType;int HealthStatus;int SpindleSpeed;int MediaType;
};

实现文件 .cpp

#include <Wbemidl.h>
#include <comdef.h>
