Samsung 840 Pro 256GB SSD Review - Benchmarks - Power Testing

Samsung 840 Pro 256GB SSD Review
In the enthusiast SSD market two products stand taller than the rest - the OCZ Vector and Samsung's 840 Pro. Today we're looking at the 256GB capacity size. Two drives enter, one drive leaves the champion.

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.




Our test notebook hasn't been optimized to run for ten hours, we did this to reduce the time needed to run this test. In our test, the Samsung 840 Pro delivered around 10 extra minutes of battery life over Vector. The 840 delivered nearly 20 more minutes over the 840 Pro.

Here we see where the extra battery time came from. Samsung's 840 class drives use far less power at idle than Vector, an important feature for notebook users since most of the time your SSD is idle.


The idle time is where Samsung has an advantage, but with just these three drives on the chart, we see that Vector actually uses less power when active. In consumer tests this isn't all that important, but in enterprise tests were drives are busy more than they are idle, it might be enough to shatter Samsung's presumed lead as the low power leader.
