【问题描述】：

我正在编写一个 Hyper-V 虚拟机构建脚本，并希望添加一项功能，以便在可能的情况下选择 SSD，以优先考虑较小且最常用的虚拟机。我首先从这里的脚本专家那里找到了方法：http://blogs.technet.com/b/heyscriptingguy/archive/2013/03/17/powertip-use-powershell-to-identify-ssd.aspx，但我找不到任何可以带我一路走来的东西，所以我使用 WBEMTEST 来查找我需要查询的类，以便在 SSD 磁盘和有问题的驱动器号。

单击开始 --> 运行 --> 键入 WBEMTEST --> 检查命名空间是否设置为 root\cimv2 并单击连接 --> 枚举类 --> 递归 --> 确定。大约 5 秒后，列表将完全填充，允许您单击列表项。单击列表项，然后按字母 W 跳转到 Win32 并找到要查看的项，然后单击添加。然后显示可用的属性和方法。

下面的函数 IsSSDDrive 返回 $True 或 $False，具体取决于给定的驱动器号（包括冒号 - 例如 C:）是否安装在固态磁盘 (SSD) 上 - 假设制造商将字母 SSD 插入到设备中姓名。这种假设最终使这种方法变得不可靠，因此明智的做法是包含一些代码以使用以下代码进行交叉检查：

$DiskScore = (Get-WmiObject -Class Win32_WinSAT).DiskScore
If ($DiskScore -gt 6.9) { $SystemHasSSDDrive=$True } Else { $SystemHasSSDDrive=$False }
Write-Host "System Has SSD Drive: $SystemHasSSDDrive"

...如果您的环境使用此类驱动器。

# Returns $True or $False depending on whether the given drive letter (including colon - e.g. C:) is mounted on a Solid State Disk (SSD) - assuming that the manufacturer inserted the letters SSD into the device name - which ultimately makes this method unreliable so beware to cross check using something like $DiskScore = (Get-WmiObject -Class Win32_WinSAT).DiskScore # Thanks to Rens Hollanders for this! http://renshollanders.nl/2013/01/sccm-mdt-identifying-ssds-from-your-task-sequence-by-windows-performance-index/

这里是主题的一个转折点，以防这是您需要的。此函数返回一个 SSD 驱动器号数组 - 如果找到的话

Function GetSSDDriveLetters()
# Returns an array of SSD drive letters - if any are found - assuming that the manufacturer inserted the letters SSD into the device name - which ultimately makes this method unreliable so beware to cross check using something like $DiskScore = (Get-WmiObject -Class Win32_WinSAT).DiskScore # Thanks to Rens Hollanders for this! http://renshollanders.nl/2013/01/sccm-mdt-identifying-ssds-from-your-task-sequence-by-windows-performance-index/

#return letters of disks and if SSD or HDD or Unspec..:

    $physicalDisk = $_ 
    $physicalDisk | Get-Disk | Get-Partition |
    Where-Object DriveLetter |Select-Object DriveLetter, @{n='MediaType';e={ 
    $physicalDisk.MediaType }}

【解决方案3】：

这是我检查当前工作目录是否在 SSD 上的版本：

function IsWorkingDirectorOnAnSSD {
    $DriveLetter = $pwd.Path[0]
    foreach ($Drive in Get-PhysicalDisk) { 
        if (($Drive | Get-Disk | Get-Partition).DriveLetter -Contains $DriveLetter) {
            Return $Drive.MediaType -eq 'SSD'
        }
    }
}

这可以用驱动器号作为参数进行修改，以通过驱动器号检查。
