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 Samsung 850 EVO 1TB does a bit better than the 850 Pro 1TB in the same capacity when it comes to notebook battery life. For this test, we don't have the drives beat down to where the advanced error correction is in play. One of these days, we'll take a handful of TLC drives, and wear the flash to the point where the advanced ECC has to kick in. This will allow us to see what happens to the power consumption when the drive has to read the same data from the TLC flash a few times. Given that the 850 EVO uses the next best flash right after SLC, I don't think this product will have any issues for a long time.

 

Power Limited Performance

The performance rating is a bit lower on the 850 EVO than the 850 Pro in a power-limited environment. Notebooks reduce the bus speeds to the CPU, PCIe, and SATA components to reduce power consumption. Some SSDs do slightly better than others in this reduced power state do. I doubt anyone would actually notice a difference from one drive to another since the latency increases on all drives.
