i have tried to research about the power consumption issue about this SSD but not too much information about it. It is a fast drive but i m wonderful it will drain more battery compared to the original HHD. btw, I am using the macbook 13 2011 model. because i am planning to buy the 240gb model. thanks
Got a tip for us?

does Vertex 3 has serious Power consumption problem?

I've been using it for about a month on a 2011 15" and I haven't noticed any decrease in battery life.
The Vertex 3 has relatively high idle power consumption. If you want maximum battery life there are better options.

Many power measurements:

As you can see different websites come to different conclusions, because there are many ways to measure.

I seriously, seriously doubt switching one SSD for another would make roughly an hour of battery life's worth of a difference. That's just crazy-talk. These things don't draw that much power.
That battery test must be totally borked in its methodology.
One might want to note that fast SSDs can actually use even more power than a HDD, particulary on a system-wide level, since they're so high-performing. This allows them to get (much) more work done per time unit, and the CPU and its related subsystems (memory, misc. I/O) will work harder to feed the SSD with data.
The upside is that since one typically do not load the disk with I/O requests constantly, a SSD will allow the CPU to get done with its task quicker than a HDD would, and thus go into powersaving idle mode faster.

I also have a vertex 3, and haven't noticed a difference in battery time.
I do some pretty heavy work though. It's possible that if there is a greater power consumption, it's being offset by the fact that the drive isn't active for as long.

The reviews clearly show there can be more than 1 watt difference. The total power draw of the MBP 13" can be around 7 watt if you turn down the brightness and disable bluetooth. If the total battery life is about 7 hours, then 1 watt less will result in ~1 hour more battery life.
Crucial M4 has lower idle consumption. If you want to reach max. battery life during low intensity use the M4 will do better than the Vertex 3.
I can confirm this myself, I got about 1 hour more with the M4 than with Vertex 3.
Tomshardware also showed huge difference in battery life between SSD. Noticeable the Intel X-25m was very easy on battery life.
I don't think this benchmark is wrong because I have seen the same in other benchmarks.
