For TRIM to function, both the SSD and the operating system must support TRIM, and be enabled in the operating system. Verify that the SSD supports Trim by using the Intel® Solid-State Drive Toolbox to view the drive attributes:
- Open the Intel® Solid-State Drive Toolbox.
- Click Export.
- Save the .csv file and open it in an appropriate tool, such as Microsoft Office Excel*.
- Find 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.
||If the drive does not support TRIM, check to see if a firmware update with this feature is available. |
Check the operating system to see if TRIM is enabled:
At the prompt, type %root%:\>fsutil behavior query disabledeletenotify.
Open a Command Prompt as Administrator.
- Go to Start > All Programs > Accessories.
- Right-click Command Prompt and click Run as Administrator.
DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
DisableDeleteNotify = 0 (Windows TRIM commands are enabled)
1 The 34-nm series Intel® Solid-State Drive (Intel® SSD) drives with firmware 02G9 show the Hex Value as 0 because this firmware version does not support TRIM.
