I have an OWC Mercury Extreme Pro 6g 480gb via Velocity Solo X2 PCIe Also, I have a Samsung 840 EVO PRO via Velocity Solo X2 (Separate cards) Per this article it states "If you have an OWC SSD, though, you dont need TRIM. The SandForce controller in our SSDs takes care of this garbage collection...enabling TRIM could actually hurt the performance and reliability of your OWC SSD, rather than help it" However, I understand I must enable TRIM for my 840 Evo Pro. The thing is, I can't enable TRIM for certain drives. It's either on for ALL or no TRIM whatsoever. How do I keep TRIM for my 840pro, but not for my OWC ssd? Is this even possible?
