PowerShell: Quick Script to Get Storage Utilization

$volumes = (gwmi -Class win32_volume -Filter "DriveType!=5" -ea stop| ?{$_.DriveLetter -ne $isnull}|`
        Select-object @{Name="Letter";Expression={$_.DriveLetter}},`
        @{Name="Label";Expression={$_.Label}},`
        @{Name="Capacity";Expression={"{0:N2} GiB" -f ($_.Capacity/1073741824)}},`
        @{Name = "Available"; Expression = {"{0:N2} GiB" -f ($_.FreeSpace/1073741824)}},`
        @{Name = "Utilization"; Expression = {"{0:N2} %" -f  ((($_.Capacity-$_.FreeSpace) / $_.Capacity)*100)}}`
        | sort -property Letter |ft -autosize | Out-String).Trim()
write-host "Current storage stats:`r`n$volumes"
Sample Output:

Current storage stats:
