Power consumption: SSD is not so good?

Tom's Hardware has published the results of a study of the performance and operating time (english) of a laptop using conventional mechanical HDDs and, actively advancing now, flash SSD.

As an active user of laptops, it was useful and interesting for me to read the entire article in its entirety, but, by and large, the most "tasty", of course, in the chapter " Conclusions :"

If you are using flash based SSDs. As a matter of fact, most flash SSD products contribute to your battery even faster! Mainstream flash SSDs - even if you can’t even be called “mainstream” at a price of $ 500, it’s not a problem.

The results of our tests can shock anyone who cares about laptop battery life, since they accurately indicate that the battery life is not only not increased when using SSD, but on the contrary - it decreases! The available flash SSDs (if you can call them “affordable” at a price of $ 500) with lower performance than conventional HDDs, they will also “eat off” the battery of your laptop faster.

However, in the same place, a little further, there is a soothing note in the style of “but by buying an expensive SSD you will get a good performance.” But the meaning of the acquisition of a sub- or compact laptop on an SSD already makes sense to think.
