Desktop Test System
Lenovo W530 - Mobile Workstation
We use two systems for SSD testing. The desktop runs a majority of the tests and the Lenovo W530 runs the notebook power tests as well as the real-world file transfer benchmark.

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.
Intel's 525 Series is the latest addition to the LSI SandForce mSATA products so we chose to use it for our comparison to Kingston's early B02 mSATA drive. It doesn't get any more on the level than comparison. The Intel 525 Series just hit the market; our review isn't even published yet. The Kingston B02 early sample is the SandForce of the future and in this chart we see a thirty minute increase in battery life.
Since this is all about battery longevity and power use, the question that we expect to hear is about Samsung. Why didn't we include a Samsung 840 Series mSATA drive in the chart? We simply don't have a Samsung 840 Series mSATA drive to compare to, and neither does Samsung. Our Samsung 840 Pro 128GB 2.5" drive scored 251 minutes in this test and our 840 non-Pro 250GB 2.5" drive scored 290 minutes.
PCMark Vantage HDD Test - Power Draw
In this test, we record the 3.3 volt line going into the mSATA SSD to measure current. This allows us to see where each drive makes improvements. We brought another drive into the charts, an ADATA SX300.
We often hear, especially in forums, that one LSI SandForce is the same as all of the others. That simply isn't true. Even if the controller is the same and the flash is the same, manufacturers still need to choose many other components to get to a working SSD.
Power regulation circuitry is an area that varies widely and has a direct impact on performance, stability and power efficiency. We're not trying to pick on any particular brand or manufacturer here; we just feel it's important to show the differences and exactly where they are.
