Is there any way to partition the SSD portion of a Fusion Drive? I'm looking at my next computer and am debating on whether or not to invest in a Fusion Drive. I'll be using Windows heavily on it though, and would like to take advantage of the SSD on both operating systems rather than just from within OS X.

I'm pretty technically savvy, so I wouldn't mind using Windows, Linux or another operating system to accomplish this task.

Thanks!
Since FusionDrive is really Corestorage with some added magic (or supposed to), there is no mandatory reason to assign the whole SSD to the Fusion drive.

When creating you DIY Fusion drive, just reserve space by creating adequate partitions and refer to the partition ID (diskXsY) instead of the whole disk.
