Apple unveils Fusion Drive for new iMac and Mac mini

And even for that model its only available in 1TB not 3TB.
Note that there is no longer an option to buy large dual 7200rpm drives for any model of Mac mini.

There's no way that would be reliable enough to support as an official feature. Even if the drive was directly connected, I can't see them doing it. What happens if the drive is disconnected?

I also wonder what security model this has. When you use Ableton Live, by default your sound library is in ~/Users/<user>/Library/Application support. When you use those large sound loops often enough, do they get moved out of platter to SSD spaces and then lose permissions/become more easily accessed, or is all this optimization magic happening at a more fundamental device block level or... ???
What if the SSD only has 2GB free and you have a 4GB frequently access data file (favourite HD movie maybe)? Does the file system block-move to SSD portions of the data or does it lock it from being moved until its whole can be addressed?
I don't know if I want to give up that much "easy for a human to manage" intelligence to a storage/optimization algorithm. I would what use file integrity/recovery applications would be with this new layer of magic?

I was just about to pull the trigger on a Momentus XT this morning... and now there's something better. I wonder how long it'll take the aftermarket to catch up?

What's describd in the article, is exactly what is claimed for the XT. Until performance comparisons are published there is no way of knowing if the Fusion Drive is "better" or just a new name on existing tech.
Until the teardown, we won't know just how upgradable these machines would be. It could be that the only practical way to install a hybrid drive is to order it that way.

well, we can guess: the Momentus XT has 4GB of flash on its little SSD. The Fusion Drive has 128GB on its SSD. That's quite a jump, and means the drive can permanently leave A LOT on the SSD. The Momentus could barely (or not) store the OS and a few favorite apps.
