If I understand correctly, TRIM is used on SSDs without dram cache to clean up the drive after a cirtain number of writes so the drive can keep its speed up. I take this information from this video https://youtu.be/v7YBCynA-b0 (they are not fool prof but it seems logical.)
So as I understand it, you need TRIM support on cheap SSDs without dram cache but not on expenses ones with dram cache. You might need a turn off the drive program to sync to disk from cache but I am not sure.
