I'm about to buy a new Mac Pro, and I really want an SSD, but I'm not sure what the best way to go about it is. All of my digital video is going to be on a separate drive, but I want an SSD for my main. 512gb is enough for everything else I have, but I'm worried if I have all of my applications, photos, etc on the same drive as my OS that I may be compromising the performance, both because of accessing too many different things on an individual drive, and also because the drive will just have a lot more stuff on it and not a ton of free space. So my question is should I get: 1. A 512gb SSD + separate drive for video. 2. A ~128gb SSD for my OS, + an HDD for my other main stuff, + a separate drive for my video. 3. A ~128gb SSD for my OS + a drive that will hold all of my other main stuff and all of my video. 4. A ~128gb SSD for my OS, + a 256gb SSD for all of my other main stuff, + a drive for my video. I'm looking at this from all angles, including performance, power consumption, heat, convenience, and cost. I can afford any of these solutions, but I obviously don't want to spend more than I am getting a benefit from. Thanks!
