How to Enable or Disable SSD TRIM in Windows 10
Solid state drives are becoming extremely popular these days. The impressive speed and boost in system performance that SSDs offer are enough reasons for this increasing popularity. If you want a massive upgrade to your PC, replacing your old Hard disk with a solid state drive would be the way to go. This is literally the best upgrade you can do at the moment.
SSDs use blocks to store data in them and the TRIM command is a critical feature of the operating system that communicates with the SSD about what blocks of data is no longer required and can be safely removed. This helps squeeze the maximum performance from the SSD since unwanted blocks are ignored. Unfortunately, the TRIM feature is not available in newer versions of windows like 8/8.1 and Windows 10.
Windows will automatically detect the SSDs most of the time and enable TRIM, but if it doesn’t, here is how to check and enable TRIM support in windows 10. There are some easy methods to check the status of TRIM in your operating system.
Bonus tip: The same methods can be used to enable/disable TRIM in older versions of windows.
Step 1: Open the Command prompt with Administrator privileges
Step 2: Type the following command and hit enter
fsutil behavior query DisableDeleteNotify
If you believe your SSD supports TRIM and can perform better with TRIM enabled, you can go ahead and enable TRIM on your OS. All you have to do is run the following command.
fsutil behavior set DisableDeleteNotify 0
You can disable TRIM support for your SSF, just run the below command.
fsutil behavior set DisableDeleteNotify 1
It always recommended to have TRIM enabled when you are using a Solid state drive as this can squeeze the maximum performance from your system. Your system can run buttery smooth with TRIM enabled on a decent SSD.
