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.
In the introduction I said we'll take a look at the power usage difference between the SanDisk Extreme 240GB and the 480GB. Since it has more physical NAND flash I'm not surprised to see the 480GB Extreme do a little worse in this test, but I am surprised to both of these drives do worse than the Corsair Neutron GTX 480GB.
Until now I thought the SanDisk Extreme was a really good drive for notebook use. Just a couple of days ago we tested the Silicon Power Slim S70 and it delivered around 276 minutes of battery time in MobileMark 2012 1.5, more than the Neutron GTX, but still less than the Crucial m4. The two SanDisk Extreme drives were down around 40 minutes to the Crucial m4 512GB.
PCMark Vantage HDD Test - Power Draw
Before I started doing the notebook test I was only testing power while playing back a trace from FutureMark's PCMark Vantage. Here we see the SanDisk Extreme 480GB doing really well (in yellow). This test doesn't take into account idle time unless induced by the benchmark.
As you can see, the Extreme doesn't have the peaks that the other drives do and at the low end the Extreme pulls less power than the other drives.
I'll admit, we're still scratching our heads, but the results were verified in several runs.
