Do SSDs Use More Power Than HDDs?

Would you Adam n' Eve it there's a debate going on about whether SSDs use more power than HDDs?

 

Tom's Hardware says: "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."

 

Tom's Hardware reckons there's an explanation: "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," continues Tom, "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."

 

Good grief. One in the eye for SSD being the future of mobile storage.

 

However, Laptop Magazine has come up with an SSD-HDD comparison and, says it: "Tried the drives under a more "real world use" test regime: cycling through webpages over and over. And guess what? Both SSDs resulted in an extra 10 minutes of battery life, versus the native hard drive."

 

Crikey. Ten minutes.

 

 Doesn't quite compensate for the HDD/SSD price difference.

 

Maybe the future isn't what it used to be.
