I'm looking to upgrade my laptop with an SSD, preferably one with the lowest power consumption I can find. Does there tend to be general differences in power consumption between different types of SSDs (ie SATA I, II II...) or just between individual brands/models? Not much of a difference at all? I would much appreciate some input. I'm aware that power consumption will vary depending on usage, but I'm just thinking in terms of overall averages.
I have a Samsung NP550P5C-A01UB with Windows 8. Specific recommendations are welcome.
