That is close to what I am after, actually, so thanks for the tip.
I did look closely at it, and while I would love to get one, after spending ~$8K on Mac Pro and 32" 4K monitor, I have to be a bit cautious.
Basically, I need 4TB minimum, and while the 2TB Velociraptors would be awesome performance, they are roughly double the price per GB at half the capacity of what I was after.
