SSD vs Standard HD in Laptop-Battery power, any equal in power consumption?

    I was looking at an SSDrive, specifically a Kingston 60GB, for a laptop, but older posts on SSD say they consume more power than standard platter type HD's. Anyone know of a SSD that is more or less equal in power consumption than a standard platter drive?

    I'd not go with less than 120 GB with a SSD. 60 GB is not enough at all.

    Overall, I'd say that SSD's are worth it, when it comes to speed. That laptop will feel like "The Flash" compared to the slow 5400 rpm drive that most laptops are using.

    The speed you will gain will be dependent on the drive's read and write capabilities as well as which generation of SATA is on board the laptop. If it's SATA II, you will probably top out about 275 MB/s even if the drive is rated at 530/500 read/write.

    As far as power consumption, they ordinarily require less and can extend battery life a bit.

    What model laptop and drive are you looking at specifically?

    Leveno T60, Kingston 60 GB SSD. Threads on Toms and others are saying these suck way more power, which is my main issue, not speed. Lots of people on threads complaining of reduced battery life. But some are old threads, thought maybe newer SSD's would be dealing with that issue by now, but I'm not convinced.

    Older SSD's might have a higher wattage on paper but they do the same work in half the time or less = less overall power used. More recent SSD's tend to be more frugal with power than the older ones, with greater speed difference.

    Get the largest, most recent model, quality brand that you can run to - it will still be a decent addition to your next machine in a year of two.

    The SSDs that suck the most power will still suck considerably less power than an HDD.

    Hi

    I think it may have been the case back in 2008-10 when I guess many reviews talking about SSD vs HDD is power consumption where negative against SSD, but these days the modern SSDs are very good for power consumption, especially the Samsung Evo 840 range, and a review HERE They are comparing a hybrid WD Black HDD+SSD drive but it gives the standard SSD only drives results to compare with. Plus also this one SSD HERE and HDD HERE

    Best HDD in those tests 3.6w vs the best SSD at 0.30w

    Also in a laptop what you also have to factor in is that an SSD has negligible heat give off (surrounding other component heat will make a SSD slightly warm to touch) compared to a HDD, and in a tight space as a laptop this is a plus as more heat the more the fans come on and more power used.

    I put a Samsung in my Toshiba LT, have not done a time measurement but definitely runs longer, guessing maybe 1/2 hour. LT runs a few degrees cooler, plus the speed will put a smile on your face.
