Trim

Microsoft Windows 7 and newer supports TRIM for SSDs (if the disk supports it)

How to check if TRIM is enabled on Windows

To check if TRIM is enabled in Windows, follow these steps:

Press Windows + x, click Search.
Type cmd in the Search box.
Right-click Command Prompt entry.
Select "Run as administrator".
Enter fsutil behavior query DisableDeleteNotify.
Press Enter.

There are two possible outputs of running the above command:

DisableDeleteNotify = 1, which means that TRIM is disabled on the SSD.
DisableDeleteNotify = 0, which means that TRIM is enabled on the SSD.
