OK. What amount of disk capacity are we talking about? Anything up to
1TB can be done today for a reasonable amount of coin on SSD.
What are the interfaces for specialized hardware? PCIe? Interface count?
I suspect you can build a remarkably fast system inside of 150W with a
bit of research. Intel E3-series v3 Xeons/Haswell CPUs pack a pile of
performance into 60-80W - at a decent price. Especially if the software
uses recent instruction extensions eg AVX.
