SSD Upgrades before and after

There's so many opinions out there about SSD and battery life

Please respond by stating battery life Before SSD upgrade and AFTER SSD upgrade

 

The same power gets used by an SSD as a HD - the only thing that makes the SSD slightly more power-efficient is there's no motor to drive. First-gen SSDs actually used a bit *more* power than HDDs did, but every review I've seen of the current generation shows battery life is improved, but not dramatically.

 

I haven't noticed much of a difference to be honest. But the power guzzler here is the GPU, not the hard drive. It'll probably make a noticeable difference in netbooks where the CPU doesn't consume much power.

 

You can't generalize power consumption (battery life) since some SSDs can consume more while others use less power than HDDs.

 

But you can say SSD's and HDD's are minor part of the total power draw. As such you can actually say a lot.

I would say turn your screen brightness way down or off. Run your CPU and GPU at the highest power saving settings. If you can handle that then maybe the drive will make a 5 minute difference. Misplaced effort on this one is all I can say in my humble opinion.

 

Again, not always true. For a 15 or 17" system, yes, the power draw isn't much, but for a 12" ultraportable, the HDD/SSD can have significant power consumption.

 

If I give you that point. Would you not admit over 90% of the people who ask are not your candidate? But mine? Meaning not the real issue?

 

Going from a 250gb hdd to a first gen samsung 128gb I saved

0w on standby
1.5w while watching a film

which came to 1.5 extra hours on a culv system

 

I have to call shenanigans on that last post

According to the following wattage table published by University of Pennsylvania (based on real world measurements):
Approximate Desktop, Notebook, & Netbook Power Usage

An Core2Duo CULV laptop (Lenovo ThinkPad X300) will use 38-40 watts while under moderate load on battery power.

A Corei5 laptop (Lenovo ThinkPad T410s) will use 39 - 58 watts under moderate load on battery power.

An Atom based laptop (Dell Inspiron Mini 10) will use 19-21 watts under moderate load on battery power.


1.5 watts difference due to SSD will make a 4% battery life improvement on CULV laptop, 2-3% on full powered laptop, and 7.5% on atom netbook.

So if you saw 1.5 hours improvement on CULV laptop, that should make your base battery life in the neighborhood of 37.5 hours! Or your test was flawed.

 

I have NO idea where they get those power figures but they are insanely off.

Moderate load on the X300 hovers around 13-16 watts, sub 10w idle

Moderate load on the T410s hovers around ~15w, sub 10w idle

A good Atom netbook will have a load around 10w and idles around 5-6w.

(going off values I see day in and day out doing reviews)

EDIT:

AHAHAHAHAHA

"Moderate use was tested by using the latest release versions of the graphical clients for Folding@Home or SETI@Home, running in full screen mode"

They basically had the CPUs running at ~100% for their moderate test, no wonder those values are so insane.

 

No, I'd say majority of people could benefit from a drop in power consumption due to savings from a SSD. I've managed to optimize my 16" Acer to use as low as 13W on idle, which is near the range of an ultraportable. Most users do not have gaming systems and hence would not consume that much power overall. If I had the money to spend, I would get a Samsung, Toshiba or Indilinx drive for better battery life. Performance wise, Intel, Marvell (ie. Crucial C300) and Sandforce perform much better but battery life can be sometimes worse than HDDs.

 

Urrrh no...

My 1.3GHZ Core 3 duo CULV idles at 5w and goes to 7.5w watching a video.

63wh battery goes way furthur when 1.5w is saved (was 9w with hdd).

 

*** From a previous post I made ***

Power consumption for typical tasks on 1.3ghz CULV W7HP, w = watt

HDD to SSD

Idle 5.10w to 4.20w 17% decrease in consumption
Youtube 8.30w to 7.50w 9.6% decrease in consumption
Media 9.00w to 7.50w 16.6% decrease in consumption

This means on video playback I get an extra 1 hour 50 mins battery and have the file opened almost half as fast.
