Hi folks, I will do the Optibay swap on my MBP this weekend. I got an SSD 840 as a standard right now, the HD in the Optibay will be the new Seagate Hybrid SSHD with 1TB. At the moment I have about 190 gigs free on the SSD. Now the question is how to partition the HD and where to put the Win7 on it. I see two options that would make sense: 1. Put Win7 on the SSD, using a 50 gig partition. That leaves me 140 GB on the SSD. Divide the new 1TB Optibay HD in half, to have 500 GB for OSX and 500 GB for Windows 7 for storage. or 2. Leave the SSD alone and install Windows 7 on the Optibay HD only. Maybe use 600 GB for Win and 400 for OSX. Have the full 190 left on the SSD. I think from an installation point of view, option 2 would be a small problem, since I would have to do the optibay swap right away to see all drives. With Option one, I can install Win7 first and then later on do the swap. I am not sure if the OSX will let me install win7 from the "then externalised CDRom". A friend told me it is tricky because of some windows install regulations. I also have heard that its not a good idea to have an SSD filled up to its brim. There should be some space left to keep it fast. If true, this fact would promote option 2 I think. What would you do? Whats the better option? Thanks in advance!
