Tom's Hardware: We Were Wrong About SSD Power Consumption

  • MORE
As you may recall, a couple of weeks ago, Tom's Hardware posted a controversial article which claimed that SSDs actually use more power than traditional hard drives. Our own observations contradicted Tom's original claim so we set out to do our own SSD battery life tests and posted our results, showing a modest improvement in battery life with the two SSDs we tested. Now, Tom's Hardware has published a new article with an apology. They claim, as many users noted at the time, that their original test method was flawed, because it caused the SSD drives in their roundup to work harder than their HDD counterparts. The results of Tom's new test still show some SSDs eating more power than HDDs, but other SSDs, most notably the SanDisk SATA 5000 we also tested and an OCZ SATA II, using considerably less power. Of course, Tom's Hardware continues to use power meters for their tests to and while this yields very interesting results, we plan to continue our real-world testing with battery rundowns. We're getting in a slew of new drives soon and plan a performance shootout.

    Also if you have a crappy atom computer , you have more likely a cpu bottleneck.

    Try the disk in a core 2 duo and you will notice some major difference.

    I had lenovo x300 with 64gb ssd and windows xp booted in 15 seconds. Beat that if you can.

    For your knowledge my Hp 2510 with 1.8inch disk took 45seconds. (1.8inch are slower)

    So it depends what ssd you buy there are good ones as well as crappy ones.

    After reading all the hype about SSDs I purchased an Intel SSD to install in my Acer Aspire One. I did so without issue and after using it for a while I can say without hesitation it's a disappointment. Purely from a user standpoint I don't find it any fster than my old 5400rpm HDD and my Acer doesn't last any longer on the battery than it did before the install. I don't see any advantage to paying 3 to 4 times the price except that you no longer have to defrag the SSD and it is less prone to movement damage if dropped etc. I'd simply stick to a 7200rpm HDD for the price. I think we've all been sold a "bill of goods" on how great SSD's are.... BS.
