Why? This is a shipping feature that is present on new hardware available today. The HW isn't present in older models, but the SW is. If say, you were like me, and broke warranty and installed these drives anyways, then setting up a logical volume would be the exact same as using the new Fusion Drives. Remember, Apple isn't using a special hybrid drive, they are only using logical volume management and handing data transfer in SW.

Fusion drives in general aren't a good idea. If it were completely bug free it would have the same reliability as a completely bug free raid 0 config. .

Oh pardon, you are stating that the reliability is bad for an installation like the Fusion Drive, period. Not that the SW is prone to chaos when you yourself setup a Fusion Drive using the instructions in the linked article. I apologize!

Actually, replacing the RAM, hard-drive and optical drive don't void warranty in most Macs.

Hence the ability to setup a Fusion Drive myself..
