I have just received all the parts for my new daw build and am not familiar with the asus p8z68 mobo. I have purchased 1 crucial m4 128gb ssd and two 1 tb wd caviar black 6gb/s 64mb cache sata 3 hdd's. The mobo has 2 intel 6gb/s sata 3 connections and 4 sata 2 connections but also 2 marvell pcie 6gb/s sata 3 connections and 1 jmicron esata 3gb/s connection. I am not sure what connections to run my drives on for optimal performance. Sorry about the long description with the question i just don't want to leave any info out. Im a new member of this forum so thank you in advance for any advice that you could give. I posted this in another thread but i think it was the wrong one so if someone could also let me know how to delete that one id appreciate it.
