Hey Doug, I have a comment about the last line of your message -- 'Then again, if this is too much of an "edge case", I will just keep my patches in-house.' As the use of SSD's in RAID configurations becomes more common, and SSD's become faster, the case you're talking about will be a major issue preventing customers from getting all that they expect from the equipment they purchased. I would encourage you to continue pursuing better performance.
