Yesterday, as an experiment I turned off Trim in Trim Enabler 4.1.2 shut down my cMP, removed all drives except my SanDisk SDSSDA480G ( Sierra 10.12.6 ) and my Samsung 960 EVO NVMe ( EFI-bootable ) ( Sierra 10.12.6 ).
Shut down again and did a cold start.
After the startup I was surprised to see that both of the above drives showed as Trim = Yes in Sys Info..
Native, built in Trim !
I have never run the Terminal Trimforce command.
EDIT : I wonder if there would be any conflicts in running Trim Enabler with SSDs that have native Trim support ? Anyone have any thoughts on this?
^^^^^AFAIK, neither of those drives are natively TRIM supported by the Mac OS. And, IIRC, Sandisk uses the Sandforce controller, and the Sandforce controller doesn't like TRIM. I believe that TRIM was still enabled when you restarted.
