How to Enable TRIM for SSD in Windows and Verify TRIM Support

TRIM is an essential command that helps maintain the performance of your SSD by clearing unused data blocks and freeing up space. While TRIM is often enabled by default on modern SSDs, you may need to activate it manually. In this guide, we’ll explain how to enable TRIM for your SSD in Windows and check if it’s working correctly.

What is TRIM and Why It’s Important for SSDs

TRIM is a command sent by the operating system to inform the SSD about unused data blocks that can be erased. This process prevents the SSD from filling up with unneeded data, enhancing performance and extending the drive's lifespan. Without TRIM, an SSD would perform additional write operations, potentially reducing its speed and efficiency over time.

How to Enable TRIM for SSD in Windows

Open the Command Prompt with administrator rights. Press Win + S, type cmd, and then select Run as Administrator.
Type the following command and press Enter:
```
fsutil behavior set DisableDeleteNotify 0
```
If the command completes successfully, TRIM is now enabled. The command DisableDeleteNotify 0 activates TRIM support.

TRIM support should now be enabled on your SSD.

How to Check if TRIM Support is Enabled on Your SSD

To ensure that TRIM is active, follow these steps:

Open the Command Prompt as an administrator again.
Type the following command and press Enter:
```
fsutil behavior query DisableDeleteNotify
```
You will see one of the following results:
- DisableDeleteNotify = 0 — TRIM support is enabled.
- DisableDeleteNotify = 1 — TRIM support is disabled.
