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 is another test where we needed to show performance with equal capacity size products.

 

The 240GB Extreme II did really well compared to other equal sized SSDs in our notebook battery test. The Extreme II 480GB, well... not so much.

Even after looking at the power consumption in our trace test, I can't explain why the Extreme II 480GB delivers less battery life than the other capacity sizes. I suspect the answer rests with the DRAM buffer, though.

 

The 240GB Extreme II uses a Hynix 2GB and the 480GB uses a Samsung 4GB DRAM buffer. DRAM uses more power than NAND and produces more heat. Additional heat close to the notebook processor and video chip would lead to additional power consumption from the fans, so heat alone can reduce battery time.
