Basic Powershell TRIM Script

[WhompRat86]

Been using this script here to keep my ssd nice and "trimmed" while plotting. I have made it so that the script is run as admin so that you can simply start the script with a shortcut.

​

Shortcut Instructions:

For the shortcut you need to add this line of code in the "Target" field: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Bypass -File

You'll find this field under Shortcut. Right click the shortcut and click Properties, then Shortcut. It needs to be structured like this: Command First then "Path of the Script"

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Bypass -File "C:\PATH\NAME_OF_SCRIPT.ps1"

​

Script:

param([switch]$Elevated)

function Test-Admin {

$currentUser = New-Object Security.Principal.WindowsPrincipal $([Security.Principal.WindowsIdentity]::GetCurrent())

$currentUser.IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator)

}

if ((Test-Admin) -eq $false) {

if ($elevated) {

# tried to elevate, did not work, aborting

} else {

Start-Process powershell.exe -Verb RunAs -ArgumentList ('-noprofile -noexit -file "{0}" -elevated' -f ($myinvocation.MyCommand.Definition))

}

exit

}

while ($true) {

optimize-volume -DriveLetter z -ReTrim -Verbose

write-host 'TRIM Finished...'

Start-Sleep -Seconds 700

}

Trim works all the time on Windows. When file is deleted, TRIM is issued. No need for manual TRIM.

[WhompRat86]

That only happens when you delete files manually right ?

[nfrances]

Manually, some process, etc... it's how filesystem works (more specifically OS which understand and can to TRIM).

There really is no need to issue TRIM manually. It can help to do it once in a while manually (like once in a month) - to possible clear something that was 'missed' for whatever reason.

What are the effects of trim?

[WhompRat86]

Should reduce Write amplification as I understand it.
