850 EVO 500GB VS. 1TB - power consumption?

[boed]

Is there any difference in the power consumed by an 850 EVO SSD drive by size. I'm debating over which to put in my laptop and I'd like to make sure I have optimum battery life.

Yes, 1TB consumes about 3% more power in idle, 28% more when reading, 44% more when writing. http://www.computerbase.de/2014-12/samsung-850-evo-test-250-500-1000-gb/5/

The 9 mW difference while idling utterly insignificant, but the ~1W difference during load could amount to a few minutes of battery life. I doubt that matters to you? Pick the drive that has the capacity you need.

Very good to know. Thanks
