Hi, Probably not the kind of input you're expecting but it'll be helpful to someone nonetheless. If you're a huge shop where a terabyte is not really a big deal, I would urge you to check out VAST data, and some of their Tech Field Day talks on YouTube. That stuff looks pretty much bulletproof for any flash requirement; the way they deal with flash's shortcomings is insane (will need to watch the talks on YT)..
