How to TRIM Your SSD Manually – A Full Guide

What Is TRIM?

On an SSD, when you modify and delete files, old files are still there. The new data won’t overwrite the old data directly. To avoid filling the SSD with stale pages, the garbage collection (GC) comes out. It will copy the valid data to a reserved block and then erase the original block to get a new available block.

TRIM is a mechanism that tells GC what pages don’t need copying. Hence, deleted data will be left in the original block, improving GC efficiency and reducing write amplification.

Should I Enable TRIM on SSD?

In most cases, you should enable TRIM on your SSD because it can prolong your SSD’s service life. In addition, Windows 10 and later systems set TRIM enabled by default. However, you should also know that TRIM will make deleted data unrecoverable.

How to Check If TRIM Is Enabled

To check if TRIM is enabled on your PC, you can refer to this guide:

1. Press the Windows logo key + R to open the Run box.
2. Type “cmd” and then press Enter to open Command Prompt.
3. In the Command Prompt window, type “fsutil behavior query disabledeletenotify” and press Enter.
4. If the disabledeletenotify value is 0, the TRIM is enabled. If the value is 1, TRIM is disabled or not supported.

How to TRIM SSD Manually

3. Go to the Tools tab and click the Optimize button under the Optimize and defragment drive section.
