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.




This test still has me scratching my head. When MyDigitalSSD switched over to the new Toshiba 19nm NAND with 16KB page sizes they gained a lot of battery time. Granted, they also radically changed their firmware, but we assumed the NAND played a larger part in the increased battery performance.


Here we see the M5 Pro and the M5 Xtreme, both in 256GB capacity size, and the Xtreme where the new flash actually performed a little worse than the Pro with the older flash.


Of the drives shown, the Plextor M5 Pro and Extreme trailed all of the other drives in battery life.



PCMark Vantage HDD Test - Power Draw




Looking at the trace from PCMark Vantage we get a better understanding why the M5 Pro and Xtreme draw so much battery power. These two drives pull more power while in use than anything else does on the chart.
