Are SSDs Really More Power Efficient?

Posted by CmdrTaco on from the how-will-i-green-up-now dept.

Bakasama writes "Tom's Hardware compared the power performance of several available SSD cards with a Rotating HDD that was chosen specifically for its poor power efficiency. The results seem to fly in the face of current wisdom. 'Flash-based solid state drives (SSDs) are considered to be the future of performance hard drives, and everyone seems to be jumping on the bandwagon. We are no exception, as we have been publishing many articles on flash-based SSDs during the last few months, emphasizing the performance gains and the potential power savings brought by flash memory. And there is nothing wrong with this, since SLC flash SSDs easily outperform conventional hard drives today (SLC = single level cell). However, we have discovered that the power savings aren't there: in fact, battery runtimes actually decrease if you use a flash SSD.'"

    Impossible! Those results are obviously wrong!! Now go back and do the experiment. Keep doing different experiments until we get the desired results!

    How dear you try and endanger my stock portfolio?!

      The more important question is: Is there any truth to the commonly held notion that SSD have fewer moving parts than HDD?

      This will require vigorous scientific testing...

    Now I'm even happier that I paid the extra $1300 for the SSD option in my MacBook Air.

    That way it will run out of battery sooner, leaving me free to use a real computer.

  7. Power Efficient? They can barely aim! by SDF-7 · · Score: 5, Funny

    Seems unlikely to be all that power efficient to me... hauling around that huge bulk, and it sure didn't seem like Executor really made all that difference at the Battle of Endor from a capital ship perspective. (Probably because most turbolaser batteries seem to have really lousy guidance,
    after all).

    Oh... you meant those SSDs.... my bad.
