Managed to get my Pcie ssd set up and running. Using velocity x1 with a crucial M500 ssd attached (120gb) Put it in slot 2 of my mac pro 3.1 (x16 i believe) but my write speed is 142 and my read speed is 266. That seems slow for my set up. Any ideas? ---------- I have a gtx 680 installed. Currently running on 2gb of ram til delivery man beings my other 8gb sometime this century.
