It most certainly is. I've had good results with TRIM on my two generations older Samsung 830 (no issues at all). Others report problems when updating OS X without first disabling TRIM.

There are potential problems to be aware of when running TRIM on third party SSDs under OS X Yosemite. See in particular this article from the developers of TRIM Enabler.

Thanks for the info. I already saw some articles about the Yosemite issue. But heres my issue:

When i check my system info.
It says that "Trim Support = No".

Is it because i'm running Yosemite?

You have to use TRIM Enabler to first disable kext signing, then reboot, then use TRIM Enabler again to enable TRIM, then reboot again and there you go.

Just remember that before performing any OS updates (like point releases or security updates), disable TRIM and re-enable kext signing using TRIM Enabler before applying updates.
