How to Check, Turn On, or Turn Off TRIM for SSD Drives in Windows 11
TRIM is a command that optimizes SSD performance and lifespan in Windows 11.
This command tells your SSD which data blocks are no longer in use, allowing the drive to maintain peak efficiency.
You can check if TRIM is enabled for your Solid State Drive in Windows 11 by using a simple command prompt instruction.
Enabling or disabling TRIM is straightforward and can be done in just a few steps.
TRIM optimizes SSD performance and lifespan. To check, open Command Prompt as administrator and run ‘fsutil behavior query disabledeletenotify’. A result of 0 means TRIM is on; 1 means it’s off. To change it, use ‘fsutil behavior set disabledeletenotify 0’ to turn it on, or ‘1’ to turn it off.
What is TRIM and Why Does It Matter?
TRIM is a command that helps your Solid State Drive (SSD) manage deleted data, which is important for keeping it running fast and healthy.
Why is this good? SSDs need to erase old data before writing new data, so TRIM helps keep your drive fast and healthy by doing this cleanup ahead of time.
When Should You Use TRIM?
- Keep it ON: For everyday use, it’s best to keep TRIM enabled to keep your SSD working well and lasting longer.
