Windows 10: Enable or Disable TRIM Support for Solid State Drives in Windows 10

How to: Enable or Disable TRIM Support for Solid State Drives in Windows 10

How to Enable or Disable TRIM Support for Solid State Drives (SSD) in Windows 10


The TRIM command is essential to maintain the performance of solid state drives (SSDs) at an optimal level over the lifetime of the drive. TRIM functions by actively deleting invalid data from the SSDs memory cells to ensure that write operations perform at full speed. Since a memory block must be erased before it can be re-programmed, TRIM improves performance by pro-actively erasing pages containing invalid data, allowing the SSD to write new data without first having to perform a time-consuming erase command.

EXAMPLE:

1. SSD pages contain no data.
2. User writes data to SSD pages.
3. User deletes some data. Pages are marked as "not in use" by the OS, but data remains on SSD.
4. TRIM command tells SSD controller that pages contain invalid data. Pages with invalid data are cleaned.
5. Data is written back to SSD memory cells. The invalid data had been cleaned and data is able to be written to the pages at full speed.

TRIM support for SSDs is enabled by default, and is recommended to always keep TRIM support enabled. If disabled, you risk the SSD getting defragged instead of optimized (TRIM).

This tutorial will show you how to check the current status of TRIM support for SSDs, and to enable or disable TRIM support for ReFS file systems for all users in Windows 10.

You must be signed in as an administrator to be able to verify, enable, or disable TRIM support.

TRIM Support Requirements:

• Windows 7, Windows 8, Windows 8.1, or Windows 10
• BIOS/UEFI storage controller set to AHCI/SATA mode

Here's How:

1. Open an elevated command prompt.

2. Do step 3 (status), step 4 (NTFS), and/or step 5 (ReFS) below for what you want to do.


3. To Check Current Status of TRIM Support for SDDs with NTFS and ReFS File System
A) Copy and paste the command below in the elevated command prompt, press Enter, and go to step 6 below. (see screenshots below)

*Arrow fsutil behavior query disabledeletenotify

4. To Enable or Disable TRIM Support for SDDs with NTFS File System
A) Copy and paste the command you want to use below in the elevated command prompt, press Enter, and go to step 6 below. (see screenshot below)

(Enable TRIM support for SSDs with NTFS)
*Arrow fsutil behavior set disabledeletenotify NTFS 0

OR

(Disable TRIM support for SSDs with NTFS)
*Arrow fsutil behavior set disabledeletenotify NTFS 1






5. To Enable or Disable TRIM Support for SDDs with ReFS File System
A) Copy and paste the command you want to use below in the elevated command prompt, press Enter, and go to step 6 below. (see screenshot below)

(Enable TRIM support for SSDs with ReFS )
*Arrow fsutil behavior set disabledeletenotify ReFS 0

OR

(Disable TRIM support for SSDs with ReFS )
*Arrow fsutil behavior set disabledeletenotify ReFS 1






6. When finished, you can close the elevated command prompt if you like.


That's it,
Shawn

Does enabling TRIM harmful for a Windows 7 pc upgraded with windows 10 and an ssd?

Hi,

Thank you for posting your query on Microsoft Community. Let me assist you.



TRIM is a command used to prevent the slowdown of SSDs over time, due to the writing, erasing and rewriting of data. Enabling TRIM allows your SSD to find and erase the sections of a drive before you actually need them, speeding up the process.



The SSD TRIM command is an essential feature which is required to manage your Solid State Device memory. Often it happens that a lot of memory remain unused for a prolonged time. It is very important to remove those block of data in order to provide
space for meaningful storage. A block of memory is to be re-programmed and hence TRIM leverages its functioning speed by getting rid of all unused data. There is some minimum system requirements in order to check if your computer supports SSD TRIM. Your computer
must run Windows 7, 8, 8.1 or the latest Windows 10. It must have a SSD with TRIM enabled firmware and a BIOS/UEFI storage controller set to AHCI/SATA mode.

My system disk is 100% fragged and wont defrag

Hi Jawnny,

Optimization option is a great way to help your PC stay at the top speeds, however it is only applicable to traditional rotating platters hard drive (Hard Disk Drive). Before we proceed to any troubleshooting steps, we would like to
confirm if you have a Hard Disk Drive or a Solid-State drive (SSD).

If you have a Hard Disk Drive, you can follow these steps to start optimizing it:

1. Type Defragment and Optimize Drives in
Cortana Search.

2. Press Enter.

3. Select the hard drive you want to optimize.

4. Click Optimize.

Take note that the optimization may take some time depending on the number of files, drive size and fragmentation.

If you have a Solid-State Drive, it is automatically being optimized by the TRIM feature. To check if TRIM is enabled, follow these steps:

1. Press the Windows logo key +
X.

2. Select Command Prompt (Admin).

3. Type fsutil behavior query DisableDeleteNotify.

4. Press Enter.

If the command result is zero (0), TRIM is enabled. TRIM is disabled if the result is
one (1). If you have to enable TRIM feature, follow the steps below:

1. Press the Windows logo key +
X.

2. Select Command Prompt (Admin).

3. Type fsutil behavior query DisableDeleteNotify 0.

4. Press Enter.

Don’t hesitate to reach out if you have other questions.

 

Hello Maggidon, *Smile

The first results indicated that you had TRIM support enabled for SSDs formatted with only NTFS, but didn't have it set for ReFS yet.

The last results indicate that you have TRIM support enabled for SSDs formated with both NTFS and ReFS.

 

Is it ok to have both enabled with Diskeeper 16? I'm understanding one cannot format the SSD with ReFS enabled though I'm not thinking of doing that. I guess my question is, is it ok. It hasn't been enabled up to this point.

 

I used this command to enable ReFS ... fsutil behavior set disabledeletenotify ReFS 0



I won't disable it since you say it's ok but if I wanted to disable it, would I just type in "fsutil behavior set disabledeletenotify ReFS 1

 

That would be the correct command to disable TRIM for ReFS. *Smile

 

Well I'm glad you were on here Brink. I just about went over the edge after enabling it thinking maybe I shouldn't have. I wasn't sure if I should enable that or TRIM with Diskeeper 16 but I did anyway. But now that you're saying it's ok, I'll just leave both enabled and carry on. Thank you for your help.

 

You're most welcome. *Smile

 

Sahwan what about dual boots drives

 

It wouldn't matter since this apples for all SSD drives.

 

Okmate I thought that wuod be the case just making sure.
