'What is the easiest way in C# to check if hard disk is SSD without writing any file on hard disk?

I need to check in C# if a hard disk is SSD (Solid-state drive), no seek penalty? I used:

    ManagementClass driveClass = new ManagementClass("Win32_DiskDrive");
    ManagementObjectCollection drives = driveClass.GetInstances();

But its only gives Strings that contain SSD in the properties, I can't depend on that?

I Need a direct way to check that?

This will give you the result on Win10

ManagementScope scope = new ManagementScope(@"\\.\root\microsoft\windows\storage");
ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM MSFT_PhysicalDisk");
string type = "";
scope.Connect();
searcher.Scope = scope;

foreach (ManagementObject queryObj in searcher.Get())
{       
    switch (Convert.ToInt16(queryObj["MediaType"]))
    {
        case 1:
            type = "Unspecified";
            break;

        case 3:
            type = "HDD";
            break;

        case 4:
            type = "SSD";
            break;

        case 5:
            type = "SCM";
            break;

        default:
            type = "Unspecified";
            break;
    }
}
searcher.Dispose();

P.s. the string type is the last drive, change to an array to get it for all drives
