I have been reading a large number of threads on SSDs, and have NEVER had one before. I am salivating and finally ready! I have a 2011 MBP 15" 2.3, with the 750 GB HD. I have about 450 GB filled. I would like to keep this disk and add an SSD for the boot drive, and possibly other data, depending on best practices. Based on my uses and needs below, I am looking for guidance about what size to buy, what data to keep on it, and where to place the new SSD in my MBP. I do a lot of browsing and email. I so some image manipulation, and plan to use Aperture and iMovie much more, now that I have a 9 month-old baby (the wife takes a LOT of video and pics...). I listen to iTunes moderately, although with a new AppleTV 2, I expect I will rip DVDs and watch videos using AirPlay a lot more (also due to staying home more because of the baby. For some reason, they don't allow me in bars with her...). I use a VM through Parallels occasionally. So here are my questions: 1. How much data does one keep on the SSD? Should I just have the OS, and applications, and leave all data on the HD? Or will iMovie and Aperture work better if data is kept on the SSD? 2. Depending on the above, what size would you pick for the SSD? 3. I would like to get the latest and greatest SATA III, but... 4. I would have to put the SSD in the main HD slot and the HD in an Optibay or Data Doubler, which has no shock protection. 5. Would the 6 GBPS make a difference for my uses? 6. Should I keep the Parallels Windows 7 VM on the SSD? Again, with just the OS and apps, or with some data? Thanks so much! I see so many different approaches that I am a bit confused. I am hopeful that my particular details will make sense to somebody here. Cheers!
