Swindled: Solid State Drives Don't Extend Battery Life, They Shorten It

Illustration for article titled Swindled: Solid State Drives Don't Extend Battery Life, They Shorten It

Solid state drives (SSDs) are the inevitable future of mobile computing, but a new experiment by Tom's Hardware is extremely disappointing. It ends up that the touted power savings of SSDs over their moving-parts-laden cousins are nonexistent. In fact, SSDs are sucking more power than conventional hard drives. How is this possible? Tom's Hardware thinks they know.

While moving hard drives have higher power requirements on paper, in reality, those peaks are only reached when random data is being searched out. On average, these drives have become very power efficient and rarely peak even when data is being accessed.

SSDs, on the other hand, pretty much have an "on" mode and an "off" mode. That's it. So while you are using your hard drive, that mode is pretty much always going to be the "on" one. SSD manufacturers haven't focused on other power saving principles at this time. And until they do, don't expect things to get any better.


Note: the benchmarks were all completed on the same Dell laptop. A 5400 RPM hard drive would have even lower power consumption than the 7200 RPM model tested.

As for buying that new SSD for your notebook...I'd suggest you wait a bit longer, even if you have the cash. [Tom's Hardware via Crunchgear]

@Nakko: LOL, i wish i could afford it...but i would only do it if i had a load of money cuz i know in like 2-3 years the cost will b insignificant (in the sense of SSD costing less not me having suddenly a load of money)...for now i wait

p.s@MagnoliaBoy: thank you.

i honestly hope giz doesn't suddenly become comment Nazis. I mean there is a SMALL place for stupid comments (like mine which I knew was dumb but i was just bein smartass/bored) and rather the community as a whole just ignoring them and moving on instead of ONE pointing it out so repeatedly (which is exactly what an attention whore wants) and TWO suggesting the banhammer which should be a last resort not a first reaction

(i understand that this is in the realm past the slightly off-topic relevant to this article and i accept the consequences but for the next few days I feel conversations relating to this topic are necessary/accepted)
