Hello to everyone, I am really in need of some advice. I am running a mid 2010 mac pro 2 x 2.4 ghz quad core intel zeon with 24gb of ram and a hd5879 1024 mb graphics card. I also have 4 2tb drives in the bays. I am wondering if there is anyway I can increase the performance / boot time of my machine with the following components. Samsung 840 evo 250gb ssd with an apricorn velocity solo x2 pcie card. Also a ocw drive bay sata sledge if that would be a better option instead of the solo x2 card. Intake KT4004 usb 3.0 pcie card. My problem is what would be the optimum placement for these cards in the pie slots to give the best performance. I apologise if my question seems naive, but I gather if i place them in the incorrect order or wrong slot this could have a negative impact on my system. As a guideline my current system boots from cold in around 54 seconds. Any help would be gratefully appreciated. Thank you.
