Okay, I'm going to get killed for asking this again, but here goes.... I have an iMac (2011) i7 3.4 with 16GB of RAM and two (2) internal Vertex 240GB SSDs in RAID 0. I also have an internal eSATA cable running out of the bottom connected to an OWC QX2 12TB RAID set to 5. I have the RAID 0 SSDs being backed up to the QX2 via TM. All my working and archived data is stored on the QX2, however I keep active project files on the desktop as well as in the documents folder and it's getting sloppy. I use CS5 PP for me NLE and have the OS and all programs running on the Vertex RAID 0. What should I do to improve this? In other words: 1. Should I use the Vertex RAID 0 for scratch, OS, apps, etc. as I am doing it, or should I allocate on the eSATA RAID 5? 2. My OS: should that remain or be moved? 3. Same with APPs? 4. What about current projects, and archives? Should ALL data be removed from SSD or is my sloppy file system acceptable? Many thanks for any tips or suggestions!
