Hi, I'm new to this forum but have been an apple user since 2008. I have recently bought a Mac Pro (2012). I will be using it for Logic Pro. As for music production, what would the best order of hard drives be? I was thinking Drive 1 & 2 (OCZ Vector 150) set to RAID 0 for OS Drive 3 (1TB stock HD) for Logic, Sibelius, and Native Instrument contents Drive 4 (Western Digital Caviar Black 500GB) for Logic Files, Documents, Music, Photos etc... Is this the best order of drives for maximum performance for sound production? I used to have a Macbook Pro Retina but found that one HD isn't really any use! I'll be using external hard drives, Apple Time Capsule, and Dropbox for back up. What would you suggest? ---------- The main thing I was wondering was is it faster to use the two SSD's for the OS in RAID 0, or use one for the logic files? Is the drive speed that the logic projects are on important? Is the drive speed for the NI contents important?
