powershell - Powershell-检测驱动器号是否已安装在SSD固态磁盘上

Question

我正在编写一个Hyper-V VM构建脚本，并希望添加一个功能来选择SSD，以便在可能时对较小且最常用的VM进行优先级排序。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，但是我找不到所有的方法，因此我使用WBEMTEST查找查询所需的类以建立SSD磁盘和驱动器之间的连接。有问题的信。

单击开始->运行->键入WBEMTEST->检查 namespace 是否设置为root \ cimv2，然后单击连接->枚举类->递归->确定。大约5秒钟后，列表将完全填充，您可以单击列表项。单击一个列表项，然后按字母W跳到Win32并找到要查看的字母，然后单击“添加”。然后显示了可用的属性和方法。

假设制造商在设备名称中插入了SSD字母，则下面的IsSSDDrive函数将根据给定的驱动器字母(包括冒号-例如C :)是否安装在固态硬盘(SSD)上，返回$ True或$ False。这种假设最终使该方法不可靠，因此明智的做法是包含一些代码以使用以下方法进行交叉检查:

$DiskScore = (Get-WmiObject -Class Win32_WinSAT).DiskScore
If ($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。

Function IsSSDDrive($Drive)
# 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/

这是主题的一种转折，以防您需要它。
此函数返回一个SSD驱动器号数组-如果找到的话
