MobileMark 2012 1.5 is an application-based benchmark that reflects usage patterns of business users in the areas of office productivity, media creation and media consumption. Unlike benchmarks that only measure battery life, MobileMark 2012 measures battery life and performance simultaneously, showing how well a system design addresses the inherent tradeoffs between performance and power management.




The Samsung 840 non-Pro delivered one of the best battery life performances we've seen to date, but the 840 Pro falls on the other end of the scale. The 840 Pro 128GB delivers only a small improvement over the Western Digital Caviar Blue 750GB. The OCZ Vector 128GB and SuperSSpeed S301 SLC 128GB aren't power angels, but they do deliver an extra 10 minutes of battery power with our Lenovo W530 using a small 6-cell battery.



PCMark Vantage HDD Tests - Power Draw




Earlier we stated the Samsung 840 Pro has a very aggressive background garbage collection scheme and we can prove it with this power test. The 840 Pro, plotted in yellow, has an initial low power state at idle, the first few minutes of the test. After the drive starts running the benchmark the low power state changes and never returns to the low power target for the time we measured. The last few minutes are also idle state for most drives but the Samsung 840 Pro 128GB keeps pulling higher than idle power even though the tests were complete.
