"NCQ trim command" support in Linux and / or Windows

[cappy2112]

Hello,

I would like to test the NCQ trim command (Opcode 64h) on some SSDs.
I've not been able to find reliable information regarding the support for NCQ trim in the linux Kernel, nor Windows 10.

Does anyone here have some information or resources they can point me to?
(I'm not referrring to the DSM Trim command, btw).

Thanks

Several utilities are available for windows, a quick google should reveal them but trimcheck on Anandtech should be all you need.

Linux, last I know had several commands that would test it. Which brand/version are you running?

It sounds like you're referring to the DSM trim, as opposed to NCQ trim.
I did get a reply from Microsoft regarding NCQ trim, it's not supported yet, and they aren't sure if there is any benefit.
