I recently purchased a Corsair Force 240gb SSD and installed it on my 13" MBP (2.24ghz, mid-2009, running latest version of Lion). I picked out this SSD specifically because it is better than most in power consumption (at least according to tests), but it seems to be actually decreasing my battery life, by 30-60 minutes, relative to the Seagate momentus 7200.4 320gb drive that I replaced it with. I installed and activated Trim Enabler, but other than that, the software is the same as that previously used on the Seagate drive. I examined running programs with Activity Monitor, and saw no unusual activity that would obviously drive up energy consumption. With the Corsair SSD, I not only notice the faster access times, but also that the MBP runs cooler and quieter, with the fan rarely going on. That should indicate reduced energy use, but that doesn't seem to be the case. I'm wondering whether the increased energy use is the cost of putting a non-Apple SSD into a MBP, or whether there are some settings I can tinker with that would reduce energy use by the SSD. Can anyone out there with an SSD in their Mac portable share their experience, or suggest a solution. If there isn't one, I'm inclined to put back the Seagate and put the SSD in my Mac mini.
