Sorry, as I said in other post I got a Mac pro 2010 and this is my first one. I got 3 SSD 2 of them are using this http://eshop.macsales.com/item/Other World Computing/MM35A52CMB/ and I put them in the optical drive but there is just one extra cable and I have 2 ssd which I want to run them as Raid 0. Which will be for my scratch, etc. What do I need in here? The other one it will be the main where i will install my OS and Apps. I was thinking in getting this for the Main http://eshop.macsales.com/item/IcyDock/MB882SP1S2B/ Please let me know what cables do I need since Im unsure and I really want to turn on this machine ... I got it today and I realize that I can't use it which sucks but also is my fault since I dint inform myself well.
