Smile HELP (SSD Fusion External Issues)

I have some problems I need some help with.

Here is my plan to get a 27" iMac with Fusion drive but remove the fusion and then install windows on the 128GB SSD and get an external 256GB SSD and install OS X on there then format the 1TB drive as ExFat to store data for both Windows and OS X.

Would this set up work as I do not know how the fusion works if it is possible ? I have been waiting for so long to get the new iMac but the Fusion drive was a let down for me as it will not work with Windows and that is essential in my purchase as I do not wont to pay the price for the SSD upgrade 750GB from apple.

When Bootcamp creates a partition for a fusion drive, does it put the entire partition on the spinning disk?

Yes that will work, im doing something similar, but i am going to install a 512GB SSD in place of the normal HDD. I will install windows on the 128GB SSD and OSX and apps on the 512GB SSD. Then i will get an external usb3 or thunderbolt drive for my media.

Yes once u install Windows onto the Fusion drive it will not use any of the SSD so my only option for SSD other than pay the massive price of apple 250GB SSD is go for an external SSD.

You can't install bootcamp onto an external drive.

I have asked the question before and got linked to this http://forums.macrumors.com/showthread.php?t=1414769 I am still confused if this is possible or not on the new iMac that is why I was going to split the Fusion drive and use an external SSD for OS X.

I've done it with REFIt but dunno' if it'll work with the 2012 iMac. (I imagine it would, but that's not very consclusive, is it?)

torana355,

How are you installing windows on a internal 128GB SSD and OSX on an internal 512GB SSD at the same time? Or am I reading you wrong?

Are you planning on opening the unit? I haven't seen a tear down of the 27" so not sure if it will fit 2 SSD's. I also verified with Apple that the Fusion drives are physically fused together (i.e. if you take it out, its both that will go, you can't physically split them). Logically splitting them, I've been seeing people on the forums do they then add the external but, not 2 SSD's inside the unit. Or, is this on your older 24" model?

Just wanted to know if you heard something?

Thanks!

Yes i will open it up and replace the factory HDD with a 512GB SSD and leave the factory 128GB blade style SSD in place, i will then break the fusion link in terminal so i have two logical drives. The drives are separate, they are not physically joint together.
