Answer 1

Hi,

Trim should be enabled for SSD, please use the following command to check if Trim is enable:

fsutil behavior query DisableDeleteNotify

If you see DisableDeleteNotify = 1 , TRIM is disabled. This is a problem if you have an SSD.

If TRIM isn’t enabled and you’d like to enable it, you can forcibly do so by running the following command in an Administrator Command Prompt window:

fsutil behavior set DisableDeleteNotify 0

Thanks for your time!
Best Regards,
Anne

I have this issue as well. Created a Raid0 in windows 10 using 2 NVME disks, and the raid and I'm looking forward to find a way to enable trim for my raid.

Here is info about the raid:
