Correct, I had gone back and forth between RaidZ2 and a pair of Mirrors. I needed the space to be extendable, but I calculated my usage growth to be below the rate at which drive prices were falling, so I could budget to replace the current set of drives in 3 years, and that would buy me a set of bigger ones when the time came. I did also investigate USB3 external enclosures, they're pretty fast these days. -- I apologize if my web client has mangled my message. Richard
