I am sure I am doing it wrong. When I bought my 2011 iMac i7 3.4, I hired someone to install and stripe two Vortex 240GB SSDs and install an eSATA plug to connect my an OWC Mercury Elite-AL Pro Qx2 8TB Raid 5. (Affordable Thunderbolt drives, if any, weren't avail at that time.) I have both my project files and my apps on the stripped SSDs. I know this is wrong. I don't know how scratch works exactly (spooling as renders or something) and in old days I remember being able to allocate space just for that. In any event, I have read here that I need Apps on one drive, project files on fastest, and then I guess archives and other files (incl TM back-ups) on another. Right now the latter is on the Qx2. I have waited for SSD and Thunderbolt prices to fall to an affordable point, so is this 2011 worth adding to, or should I wait and buy a newer iMac to upgrade everything. And how? Do I separate the two SSDs from the 0 Stripe so as to have one for apps and one for projects (240GB is a lot for apps no?)? If so, how do I do that? What about Thunderbolt? Is it as fast as the internal 'bus' (does an iMac even have a bus?)? How can I leverage what I have to do it right? As mentioned above, I need to get my wife a new machine as hers is about eight years old. I can either give her mine and have her help with editing (preferred) and just get another and set both up as well as I can, based on any advice given. That leads me to my last question: is an old 2006ish Mac Mini good enough for a networkable file server and if not should I get a newer one also? Does anyone have any exp with networking two iMacs for video, using a server like a Mini who can ring in?
