rotational drive vs ssd laptop temps

I've switched some of my laptops over to SSD drives and it seems like all of them run about 3* lower since the switch, thus leading to my fan running less and longer battery life. Anyone else run into this because most seem to say there is no extended battery life with an ssd upgrade.

 

Fans in laptops don't account for that much power draw, but SSD's can use as much power as HDD's can, depending on who makes the drive. I can't give you much personal evidence since I stuffed a power hungry SSD (Samsung 830 256GB) into an already power hungry notebook, so I can't say I've seen any differences

Oddly, I haven't noticed any temperature differences, either.

 

No, most actually say that there will be a massive increase in battery life with an SSD.

The facts are this: if a storage subsystem is mainly used at idle - then an upgrade to an SSD will probably give better battery life (not all SSD's though...).

When a storage subsystem is pushed though - an SSD can use just as much power as a mechanical HDD - but it will finish a set workload faster, so assuming it is one of the 'good' SSD's with lower than HDD idle power consumption - it will still offer better battery life than a mechanical HDD.

In real life though: we tend to use the capabilities of our equipment to the fullest and rarely continue doing what we 'used to do' - what this means is that we won't continue to do our 'usual, set workload' we will do more (simply put; we will push the platform and our storage subsystem continuously) which means in the end we will get more productivity, but less actual battery runtime.

Like you, I too have noticed the quieter computing experience (fans, etc.) and the cooler keyboard and chassis of my systems - while these may contribute to a very slightly longer running notebook on battery power, the biggest benefits are the lower noise levels imo.


I'm curious where you saw that 'most' say SSD's don't contribute to longer battery life - in my corner of the world, I have to convince people that not all SSD's offer that benefit by default.
