I am not willing to use windows without the SSD speeds or pay for 768GB of flash storage :( Is there any way to keep the 1TB drive as standard and add my own 256GB SSD option after i buy the 27"? I do really like the idea of the Fusion drive but when it will not give any boost to windows that I use a lot to watch Blu-Ray disks and other applications I am not liking the idea at all.

Now my options are to buy the new iMac void the warranty and add my own SSD :confused: Pay for Apples overpriced 768GB or RAGE at the slow speeds of standard HDD speeds when using windows :( Please help me decide :apple:
 
after all I think thats the best ssd option. fusion drive might be cool but i want to have control over my files and the price seems to be the same. make shure you get a seagate thunderbolt adapter and a crucial m4 (128 / 256gb) ssd, that combo seems to give excellent performance on a low budget

The problem with the goflex is that it is a one way dead end. There is no TB pass through to daisy chain anything. So then you only have 1 TB port left. Hook up a firewire adapter and your out. I think in a few months or so we will have some real options for this from caldigit and owc etc.
 
I use windows on my iMac at work and would like to purchase a 2012 one for home. I think the best solution is to use the internal 128gb SSD for the windows partition and have an external usb3 SSD for OSX.

So you will not have fusion drive but will get plenty of room for windows, a cheap and fast option for OSX (128gb SSD should be enough) and 1tb for general storage.

That looks pretty messy. I want the 768 SSD, but I'm afraid it's going to be cost-prohibitive. In that case, I'll probably go with the 1TB fusion and just use windows on the regular HDD part. I'll only use Windows once in a blue moon for games anyway...

Yeah TB isn't supported in windows. What about a firewire 800 or USB 3 drive with windows installed on it?

What boost do you need to watch Blue-Ray disks???
 
Because im booting into windows nearly daily from OS X and boot times will be horrid. ;)
 
I'm having the exact Same Problem as the OT. Would it be possible to Order the 27" iMac with the 1TB Fusion Drive then Split up the two harddrives via diskutility and just use the SSD for Bootcamp and Osx?

Yes, that is possible. :cool:

However,

A 128GB of SSD is pretty marginal for splitting into two drives for Windows and OS X. It is really too bad there isn't a 256GB option.

You will have to drop into Terminal and use the Unix commands to "break" the Fusion join and revert the coreStorage drives back to normal, Disk Utility will not do that at this time.

If you had a larger SSD, you can rebuild the Fusion drive with the OS X portion of the SSD, leaving the Windows SSD partition alone. It will work fine, I have this running on a Mac Mini. However, with the small SSD available for the iMac, you will probably not be able to effectively utilize the tiny OS X partition for a Fusion drive.

Once iMacs are available and it can be seen what Apple has done with the design, there may be opportunities to replace the internal SSD with a larger size which will make doing what you want to do more feasible.

Hey thanks that's all i needed to hear. That just saved me 1300$ for the 768 SSD :) I don't plan on using the OSX Partition so the small SSD won't be a problem for me. Is there a description on how exactly i split up the fusion drives and install windows on the SSD. Any help would be greatly appreciated.

The required commands to "break" the Fusion drive are:
(note: you can use diskutil list and diskutil cs list to obtain the volume ID's on your computer)

diskutil cs deleteVolume < insert fusion logical volume ID here >
diskutil cs delete < insert coreStorage logical volume group ID here >
