How to enable or disable Trim of SSD

Trim plays an important role in SSD performance. In the previous article, we discussed whether Trim of SSD should be enabled or disabled . No matter which option, how to enable or disable Trim of SSD is very important for computer users.

Before enabling or disabling Trim, we need to learn to determine the current state of Trim.

How to check whether Trim of SSD is enabled or disabled.

1. Press the Win+S open the Search window, then type cmd and click Run as administrator.



2. In the opened Command Prompt window, type the following command, and press Enter.
fsutil behavior query disabledeletenotify



If the query result is "DisableDeleteNotify = 0", it means that the SSD has supported and enabled the Trim command;
If the query result is "DisableDeleteNotify = 1", it means that the SSD has not enabled the Trim command.
