zfs ?

Nope. Though I would think something like Seagates Momentus XT setup would be a better performer (being hardware level based). But this setup definitely allows for much larger SSD space.

Hmmm... Now I want to order that second drive kit... haha
Stuff.

Unfortunately Apple pulled the plug on their brief flirtation with ZFS just before Snow Leopard (10.6) was released, IIRC. See these three articles for that story. I should point out that ZFS is apparently useable for "secondary storage," just not by default and not on your system volumes, etc.

Fusion Drive is something different; Apple's basically using software to weld separate SSD and spinning HDD into something better than Seagate's hybrid Momentus SSD+HDD devices. More details from AnandTech or PCMag. My skimming of the explanations make Apple's approach sound more like hierarchical storage management (HSM) applied to the two devices, versus pure caching where the capacity of the cache is "lost" to the end-user. IOW with 1TB of HDD and 128MB of SSD, Apple gives you more like 1.12TB useable storage whereas a hybrid self-contained device would give you 1TB.

Way back when I was working on number plate recognition stuff... I was mucking about with zfs, mirroring root zpools, etc.. and just one note of warning: The MacFUSE ZFS stuff is completely incompatible with OpenIndiana zfs on commodity external USB drives. I don't remember the specifics but it was one of those you wanted to kick something events, I've tried hard to forget. ( http://code.google.com/p/macfuse/ )
