How to check if TRIM is enabled?
For TRIM to function, both the solid-state drives and operating system must support TRIM and be enabled in the operating system.

Verify first that the Solid-State Drive supports Trim. This can be done by using Intel® Solid-State Drive Toolbox to view the solid-state drive attributes.

1. Open the Intel® Solid-State Drive Toolbox
2. Click on the Export Button.
3. Save the .csv file and open it in an appropriate tool (e.g. Microsoft Office Excel*).
4. Locate Word 169 and check the value for “Bit 0 - Data Set Management Supported”.

If the Hex Value is 1, the drive supports TRIM.

If the Hex Value is 0, the drive does not support TRIM¹.

Check the operating system to check if TRIM is enabled.

1. Open a Command Prompt as Administrator.

   Note Go to Start > All Programs > Accessories > Right-click on Command Prompt and select “Run as Administrator”

2. At the prompt, type: %root%:\>fsutil behavior query disabledeletenotify

   DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
   DisableDeleteNotify = 0 (Windows TRIM commands are enabled)

¹ The 34nm series Intel® Solid-State Drive (Intel® SSD) drives with firmware “02G9” will show the Hex Value in 0 because this firmware version does not support TRIM.
