Does Power-Saving Technology Kill SSD Performance?

Testing Details And Test Platforms

Testing Details

We ran two system setups that were technically identical except for the motherboard: first we tried Gigabyte’s EX58-UD4P motherboard, followed by Supermicro’s X8SAX in the second set of runs. In the first run we enabled all available power saving mechanisms (for the processor and the platform) and we gradually disabled some of them when doing additional runs. We even switched off virtualization technology in a sixth run, to check whether or not such a feature would have an impact. As you will see on the following pages, all of the power related features have a measurable—and sometimes even noticeable—impact on the performance of the X25-E flash SSD.
