From my point of view (encrypted Core Storage underlying my ZEVO home directory since mid-2012): I'm not yet convinced that it's stable in all situations. Off the top of my head, just one possible caution: http://apple.stackexchange.com/question ... 1844_52920 – that's not a discouragement from combining the two pool technologies, just a hint to expect the unexpected in edge cases.
… the composite disk is just a concatenation, though; except in one special case, writes will go to the first physical volume until that fills, then to the second physical volume. (the special case is if the first PV is a solid state disk and your particular kernel supports fusion drives; not all 10.8.2 or 10.8.3 kernels do).
That's most useful. Do we have authoritative references?
