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 power charts are starting to get a little difficult to single out an individual drive so we isolated a couple of models below.
Intel's claims of better battery life with the 335 when compared to the 520 with 25nm NAND are accurate. Intel still isn't up to Samsung's 840 battery power time, but the 335 is very close.
PCMark Vantage HDD Test - Power Draw
The same is true for our Power Over Time test with Vantage.
Here we see the same three drives singled out and can start to understand where the power savings come from. The power use when writing data is about the same, but the 335 does peak a little higher when working with random writes.
The Samsung 840 250GB has the lowest idle and sequential read power draw, but as you can see here, the sequential writes and random writes take more power. The high peaks are random writes and the Samsung 840 spikes much higher than either of the two Intel drives.
When looking at the two Intel drives, the 335 has a much lower idle power draw and uses less power when reading data. Both the 335 and 520 use about the same power when writing data and the 335 bursts a little higher when writing random data.
