SSD VS HDD

[IFUKUPALOT]

I currently use the ASUS ZX50VW which has a 5400 rpm 2.5" hdd. I was curious as to how much of a difference it would make for the battery life to replace it with a samsung 850 ssd. What would likely be the delta time of its battery life?

It would improve the battery life but I don't know by how much. I think it would reduce power requirements by about 12W~.

Power consumption would be less and battery life would be extended. It will increase battery life. But not in 2x or 3x times

You would get better battery life, but not by a huge margin. what you would get is INSANELY faster performance. probably up to 10X speed or faster in some tasks.

Loading them yes. But it's not going to make you games run at 1000 FPS.

because of vsync? /s

I don't think game can go up that high

I am fully aware of the performance benefits. the question i asked deals with battery life.

Easier 3D Mark tests will routinely get FPS in the 1000+ on a GTX 1080 :3

Here's an older article showing the effects an SSD on a Macbook Air: http://www.anandtech.com/show/2445/16

 

It's about 15% better.

Most pc gamers disable v-sync due to its dreadful delay, also cs go is a game that exists. lastly there will be no difference in fps though textures will load much faster in games like arma.

Laptop Hudson use about 3w. Ssds use about 1w in normal laptop use. So depending on use about 15min.

Thanks for the effort in finding that article but i have to discredit it seeing as it was made in 2008, its only a 4200 rpm hdd, ssd's have changed their architecture immensely since then, and OS X is very different from Win 10 in Storage utilization.

Okay, since you're not satisfied with that.

• Power draw of 2.5" hard drives at idle as of 2014. Most fall within 1W or less.
• Power draw of SSDs at idle as of 2015. Most fall below 200mW.
• Power draw of 2.5" hard drives streaming a video as of 2014. Most fall within 2W or less
• Power draw of SSDs as of 2015 (it may be worst case, it's not labeled). Most are within 500mW, but some get up to 2W.
• macOS and Windows from a higher level view do not use storage any differently than what OSes normally actively use storage for.

How much this helps depends on how much power the system was sucking in the first place. If the total system power consumption is 15W at idle for say five hours of battery life, then adding an SSD will get you about 16 minutes of battery life.

 

My math was [ (old power consumption) / (new power consumption) * (old battery life) ] - (old battery life)
