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:/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 SCMvoid BuryPoint_GetDiskMediaType(QStringList& disk_media_type);class StorageDevice{public:StorageDevice() {};~StorageDevice() {};std::string DeviceId;int BusType;int HealthStatus;int SpindleSpeed;int MediaType;};

顺便图槽一句国内的论坛（不点名了)真的水，找了半天不知所云，还是老外的靠谱！
