Have the erasing operation done ahead of time improves performance. If you find the performance of your SSD is degrading over time, try to enable TRIM or optimize the drive. In this tutorial we’ll show you how to enable or disable TRIM support for SSD (Solid State Drive) in Windows 10.

To see whether or not your SSD has TRIM enabled, open the Command Prompt with administrator privileges and run the following command:
fsutil behavior query DisableDeleteNotify

If the DisableDeleteNotify value is zero (0), it means that TRIM is enabled. If you got a result of one (1), TRIM is disabled.

fsutil behavior set DisableDeleteNotify 0

When you need to disable TRIM support for any reason, execute this command:
fsutil behavior set DisableDeleteNotify 1

That’s it!
