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 Plextor M5M 256GB's DRAM buffer adds to the power consumption and it's difficult to get exceptional battery life with a DRAM chip present. It's been done before in the 2.5" market, but with fewer components, the mSATA makers have less to work with, so extremely efficient voltage regulators and component choice is more important than ever.



PCMark Vantage HDD Tests - Power Draw




Here we see the power consumption during a PCMark Vantage HDD test. The Plextor M5M doesn't use a lot of power when reading and writing sequential data, but the power spikes when writing random data. The spikes are higher than any other drive in the chart. It also never drops back down to idle power levels. This shows the background garbage collection working at an aggressive level.
