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.
Delivering battery life in a notebook, Crucial m4. I set you up for that one! The Crucial m4 and Samsung 840 500/512GB are the leaders in the battery test with 840 Pro 512GB just behind. OCZ's Vector uses a little more power, but is a big step up from Vertex 4, a drive that used as much power as a Western Digital 5,400 RPM notebook drive.
PCMark Vantage HDD Test - Power Draw
Here we see how both of the Samsung drives are able to deliver long battery life. They both dip down to very low idle power modes, the lowest on the chart. At times the 840 Pro actually uses less power when reading data from the drive when compared to the non-Pro 840, but the Pro has higher spikes when writing sequential data and uses more power overall.
There isn't definitive proof on the chart, but from what I see, 840 Pro is more aggressive with garbage collection than the 840 is. This makes a bit of sense since the 840 uses TLC NAND and Samsung can beat up on their MLC NAND more than they can TLC NAND.
In case you are wondering how the Crucial m4 delivers longer battery life, you can see on the chart that the m4 hardly ever breaks from idle power draw. The idle power is higher than the Samsung's idle power, but doesn't suck up anymore juice when reading and writing most data types. Random writes are the only real exception and m4 spikes like everything else.
