How to Enable or Disable TRIM on Windows 11

TRIM is an important part of modern solid-state drives (SSDs) that makes them work well and last a long time. When you remove or move files on an SSD, it leaves behind data blocks that are empty. Without TRIM, these empty blocks build up, which slows things down over time. TRIM tells the SSD which data blocks are no longer being used, which lets the drive manage itself well and free up room. Today, In this article we will explain you how to Enable or Disable TRIM on Windows 11.

In Windows 11, TRIM support is necessary to get the most out of SSDs and make sure they last a long time. By managing data blocks ahead of time, TRIM makes sure that the SSD works at its best, which improves the entire user experience. Turning off TRIM could slow down an SSD over time as it fills up with data bits that aren’t being used.

To turn TRIM on or off in Windows 11, you need to use the Command Prompt or PowerShell and certain instructions. Toggling TRIM functionality has direct effects on SSD speed and lifespan, so it’s important to know what those effects are. Whether you’re a casual user or a tech junkie, you need to know how to handle TRIM in Windows 11 to keep your SSD healthy and running at its best.

How to Enable or Disable TRIM on Windows 11

Checking the status of TRIM:

  1. Use the Windows + X keys to open the search box.
  2. Click on the Command Prompt and type cmd. Then, right-click on it and pick Run as administrator.
  3. Type the following code into the code Prompt window and press Enter:
  4. behavior searches for fsutil Turn off DeleteNotify
  5. TRIM is on if the result shows DisableDeleteNotify = 0.
  6. TRIM is turned off if DisableDeleteNotify = 1.

Resetting TRIM (if it’s off):

  1. Type the following code into the code Prompt window and press Enter to turn on TRIM if it is off.
  2. set DisableDeleteNotify 0 in fsutil behavior

Risks of Disabling TRIM on Windows 11

  • Slower write speeds: Disabling TRIM prevents the SSD from efficiently discarding unused data blocks. This can lead to a gradual reduction in write speeds as the SSD struggles to find clean space for new data, impacting overall system responsiveness and application loading times.
  • Increased write amplification: Without TRIM, the SSD needs to perform additional write operations to erase entire blocks before writing new data. This increases write amplification, which puts more stress on the SSD’s NAND flash memory cells, leading to faster wear and tear.

  • Premature cell wear: The increased write amplification caused by disabled TRIM significantly accelerates the wear and tear on individual NAND flash memory cells within the SSD. This can shorten the overall lifespan of your SSD and lead to premature failure.
  • Potential data loss: In extreme cases, with significant wear and tear caused by disabled TRIM, data loss can occur as the SSD becomes unreliable and struggles to hold information properly.

Benefits of Enabling TRIM on Windows 11

  • Better write speeds: TRIM lets the SSD get rid of data blocks that aren’t being used anymore. This makes more room on the drive and speeds up the writing of new data, making the whole system run faster.
  • Reduced write amplification: TRIM gets rid of data that isn’t needed, so the SSD doesn’t have to do as many complicated tasks like removing whole blocks of data before writing new data. This cuts down on write amplification, a process that can shorten the SSD’s life over time.
  • Keep cell wear to a minimum: TRIM helps keep NAND flash memory cells in an SSD in good shape by lowering write amplification. This means that your SSD will last longer, so you can get the most out of your money.
  • Keeps the drive in good health: If you enable TRIM, your SSD will be able to keep its best performance and capacity for longer, which will make the general user experience better.


What is the TRIM command on Windows?

The Trim order tells the SSD which parts of its storage hold old data that are no longer needed. From the user’s point of view, this information is no longer in the paper. The data is not erased from the drive when the user tells it to be erased because of how solid state drives read and write data.

Does Windows run TRIM automatically?

Unless you turn it off, it runs in the background by itself. You can run it by hand, or go to the drive’s Properties, select Tools, and then Optimize to make sure Trim is turned on.

Is TRIM better than defrag for SSD?

SD cards don’t need standard defragmentation because their read/write heads don’t move. Using the TRIM command helps an SSD’s capacity by letting trash collection and background tasks skip over data that isn’t needed or is out of date. The end result is faster writing of data and less wear on the drive.
