"How you enable TRIM on a Mac depends upon the OSX version."

10.10.5

here is what the manual says for macPro 4,1 early 2009:

You can install additional PCI Express graphics and expansion cards. Before installing a card, check its specifications to make sure it can operate in your Mac Pro:  Slots 1 and 2 are x16, PCI Express 2.0 slots  Slots 3 and 4 are x4, PCI Express 2.0 slots All four slots support 16-lane cards.

OK how about this regarding OWC SSD's:

if you have an OWC SSD, though, you don’t need TRIM. The SandForce controller in our SSDs takes care of this “garbage collection” as well as performs various other tasks that keep your drive running at optimal speed, without the drop-off that you see with other brands. Especially note page two of this performance testing expert’s report where he feels so strongly about TRIM’s inefficiency that he calls call it “half-baked”…and that’s the kid friendly version of the phrase.
