如何判断硬盘是hdd还是ssd?

小白龙

我想用powershell代码判断硬盘是否是机械硬盘, 但是使用下面的代码, 机械硬盘返回如下:
系统盘 C: 所在磁盘 ST3160811AS 原始 MediaType: Unspecified

1. $systemDrive = $env:SystemDrive
   
2. $systemDiskNumber = (Get-Partition -DriveLetter $systemDrive.TrimEnd(':') | Get-Disk).Number
   
3. $physicalDisk = Get-PhysicalDisk -DeviceNumber $systemDiskNumber
   
4. 
   
5. $mediaType = $physicalDisk.MediaType
   
6. $spindleSpeed = $physicalDisk.SpindleSpeed
   
7. $seekPenalty = $physicalDisk.SeekPenalty
   
8. $model = $physicalDisk.FriendlyName
   
9. 
   
10. Write-Host "系统盘 $systemDrive 所在磁盘 $model 原始 MediaType: $mediaType"
    
11.

7. $seekPenalty = $physicalDisk.SeekPenalty
   
8. $model = $physicalDisk.FriendlyName
   
9. 
   
10. if($mediaType -ne "SSD"){
    
11.     $mediaType = "HDD"
    
12. }
    
13. 
    
14. Write-Host "系统盘 $systemDrive 所在磁盘 $model 原始 MediaType: $mediaType"

增加两个判断项吧，，，
SpindleSpeed：
若显示 $null 或 0 则是 SSD
若是 5400/7200 (转速，机械盘特有)  则是 HDD
SeekPenalty：
显示 0  SSD  
显示 1  HDD

如果是 iscsi 虚拟盘，，则要判断总线类型，，
$busType = (Get-PhysicalDisk -DeviceNumber $systemDiskNumber).BusType
if ($busType -eq 'iSCSI') { Write-Host "iSCSI 虚拟盘}
