Note to the non-nerds: Our version of fun usually does include the increased potential for chaos, corruption, and the occasional explosion. Things that are very cool technology are not always the same as really reliable rock solid technology that should be used. This is one of those.
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. .
