Re: HD + SSD management
>The idea of merging my hard drive and SSD into one logical volume appeals to me but I'm not going to do it until it's officially supported by Apple.
It's part of OSX's CoreStorage inherited from when they were flirting with ZFS, and it's used in many a new Mac. If it goes tits-up, you have your Time Machine hourly back ups- right?
I just don't think it's Apples' style to officially sanction this on machines they have already sold you.
That said, the law of diminishing returns suggests that it won't speed up your system appreciably over your current set-up, since your OS and applications are already on the faster drive; a large part of Fusion Drive's intended appeal (when implemented on brand new machines) is to not even bother the user with the fact that there are two disks in the first place.
