As the title says, I have a Mac Pro 3,1. Here is my dilemma: Currently running Samsung 850 Pro on Apricorn Solo x1 card (runs great, really like it). I want to add a second Samsung 850 Pro and setup with raid 0, so I figure this is a good time to get a faster PCIe card for the drives. I need to use the second PCIe slot because that is 2.0. The higher ups are 1.0. The Velocity Duo x2 will cover the top fan in the GTX660. Can I go with a Solo x2 and just use a cable off it for the 2nd SSD?
