Lacking the ability to have mixed permissions from public to other, I can't use the 323.
Further, during a massive data copy (180 GB) the transfer always dies (ioErr), (many attempts and it crashes somewhere around 80 - 120 GB - never the same place or file). This may or may not be the -323, I just don't know.
So I'm returning the system to Best Buy. Looks like the more expensive Drobo will be ordered (which does not come in a less expensive 2 bay solution, alas).
