Xraid seems to be targeted towards pseudo cooperate customers -- the
controllers are independent and do not allow for failover or mixed sets.
It would not surprise me if it is not tunable with regard to cache settings
(i have searched for these tunable myself). Apple seemed to just go
redundant enough (power supply, fans) to make the product appear at a
distance like it may fit into a reliable storage category -- but once you
factor in losing half the storage to make it reliable it's cost factor is
doubled. I hope that the next generation of this product line takes this
into account.
