The price comparison with other solutions isn't really fair. The cost per PB of these storage building blocks is directly compared to complete storage solutions from companies like NetApp and EMC. In the end the cost of the complete solution they assemble these building blocks into may well be cheaper than solutions from other companies and that's the number they should be using for comparison.
