The Apple 768GB SSD is a single blade device that was originally offered for the MacBook Pro earlier this year. It is unique due to its capacity at this time.
Apple has made it difficult to configure the new 27" iMac due to their poor choices of configurations. This is even more difficult if the user wants to run bootable Windows due to a Windows limitation of 2.2TB maximum drive size:
1TB HD --- slow, small capacity, slow Windows
3TB HD --- slow, large capacity, no Windows without extreme effort
1TB Fusion --- fast for most users, small capacity, slow Windows
3TB Fusion --- fast for most users, large capacity, no Windows BootCamp
768GB SSD --- fast, medium capacity, fast Windows BootCamp
How nice it would have been to have had these options:
Your new 27" iMac can be ordered with up to 2 storage drives. They are of different technology due to size constraints within the iMac. If you choose a SSD and a Hard Disk, you can elect to have it configured as a Fusion drive.
DRIVE 1:
- none
- 128GB SSD
- 256GB SSD
- 512GB SSD
- 768GB SSD
DRIVE 2:
- none
- 1TB Hard Disk
- 2TB Hard Disk
- 3TB Hard Disk
- 256GB SSD
- 512GB SSD
CONFIGURATION (requires SSD and HD):
- none
- Fusion
Then I would have been happy!

This is how they do it for the Mac Pro with 4 drive capability to constrain the number of permutations.
