Combined Performance And Efficiency
New test methods cut the $2000 machine’s drive performance lead in half compared to our March 2011 Comparison, and four times the money now gets $2000 machine builders only twice the performance of the $500 build. There is such a thing as diminishing returns though, so we'd expect to see some value fall-off as prices increase.
Using the $500 machine as a baseline makes an efficiency comparison easier.
Overclocking actually reduced the efficiency of our $500 and $1000 machines, while the $2000 machine got a performance boost that was approximate to its increased energy consumption. A more-favorable set of drive benchmarks could have noticeably improved the big system’s placement here.
