I just installed an Intel X-25m G2 SSD in my new i7 MBP. Went smoothly (downloaded the updated firmware as part of this). 160 GB drive, plenty of room but I didn't want to put boot camp on this and I've heard there's problems with bootcamp on the Intel SSDs as well.
Anyway, I moved my regular hard drive (640 GB WD Blue) over to the optical bay with the MCE kit. Also went smoothly. This drive has 2 partitions, including bootcamp with Windows 7.
I'm happy to report, the MBP boots to Windows 7 perfectly from the hard drive in the optical bay. Didn't have to change a thing. No new installs at all. W7 recognized the new SSD, installed drivers, and had a single reboot. All of the following work fine: holding option and booting, startup disk from OS X on the SSD, and bootcamp returning to OS X from Windows 7.
I'm posting this thread from the Windows partition of my MBP at this moment, actually.
I did note, there wasn't an option to boot into a Mac partition from the optical bay (holding option on startup), only my SSD and Windows.
This is super news, allows me to keep W7/bootcamp, and not waste space on the SSD.
Hardest part of this whole swap has been migrating my /user files over to the hard drive and off the SSD. I lost all my settings in this migration. Probably some error on my part, but the machine is now set. Very happy with my configuration now. Fast SSD, plenty of storage, both OS X and W7.
