Question

High disk write IOPS on the OS disk were observed, with write IOPS exceeding 30% of the baseline disk IOPS limit of 500.

I ran performance diagnostics and this is one of the issues reported. However, how to find out what disk is this?

Can't you find the identifier using Get-WmiObject Win32_DiskDrive?

Hereby example of a script?

Get-WmiObject Win32_DiskDrive | ForEach-Object {
  $disk = $_
  $partitions = "ASSOCIATORS OF {Win32_DiskDrive.DeviceID='$($disk.DeviceID)'} WHERE AssocClass=Win32_DiskDriveToDiskPartition"
  Get-WmiObject -Query $partitions | ForEach-Object {
    $partition = $_
    $logicalDisks = "ASSOCIATORS OF {Win32_DiskPartition.DeviceID='$($partition.DeviceID)'} WHERE AssocClass=Win32_LogicalDiskToPartition"
    Get-WmiObject -Query $logicalDisks | ForEach-Object {
      [PSCustomObject]@{
        DiskModel     = $disk.Model
        DeviceID      = $disk.DeviceID
        Volume        = $_.DeviceID
        Partition     = $partition.DeviceID
        PNPDeviceID   = $disk.PNPDeviceID
      }
    }
  }
}
