SSD Heat Performance

I want to know if a SSD hard disk 2"5 is a magnitude hotter than a conventional mechanical drive.

Can I presume that a SSD hard disk is much faster then a conventional hard disk?

Unfortunately my laptop gets very hot.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Hard drives have lots of mechanical moving parts which use a fair amount of power and generate a fair amount of heat. SSDs don't have those mechanical issues - only electrical ones, which hard drives have too. – Steve314 Nov 17 '11 at 2:53

They are quite cool. And yes, they are faster.

This site prints: Temperature: because they use flash memory, SSDs barely warm up at all. The same isn't true of HDDs which can in some circumstances become as hot as 50 °C.

The idea is that SSD does not have moving parts and consumes less power. Power consumption is mostly converted into heat. So power consumption equals heat generation. The actual temperatures depend on how well this heat is dissipated and the amount of surface available to dissipate.

For a desktop hard disk, maximum operating temperatures are 65 (or occasionally 70) centigrade. Although modern drives don't generate heat very quickly, they are often in a still-air zone within the case. Also, silicone rubber anti-vibration widgets tend to prevent heat being loss through direct metal-to-metal contact with the case. Heat can slowly accumulate - I've known drives to still be getting hotter after an hour. Unless you have good cooling, it's surprisingly easy to overheat your hard drives - they tend not to die instantly, but their lives can be dramatically reduced. – Steve314 Nov 17 '11 at 2:59
Laptop hard drives really need to run cooler - they probably don't have a huge fan blowing air past them. – Steve314 Nov 17 '11 at 3:00
