I have a Samsung 840 Pro in my 2009 Mac Pro, and due to the 2009 Mac Pro only being SATA 2 I get about half the read/write speeds. I've been doing some research and I came across a SATA 3 PCI-E card that will work in a 2009 Mac pro.
I'm going to put my SSD in my second optical bay drive and run a SATA cable up to it, but what do I do about power?
