I've heard that apart from straight-up speed, SSDs greatly outperform HDDs in power consumption and heat generation. How much greater, on average, is an SSD than an HDD in:
- Power consumption.
- Heat generation.
Is there a very significant difference?
Answer
There is a considerable difference in power consumption, I've seen different data on that, but its ~0.6W as opposed to ~2.2W.
One thing to keep in mind- because there is no queuing delay, the processor utilization will go up, and that will create a lot more heat. A buddy of mine says that there are times where his laptop actually gets hotter after doing that upgrade for that reason. I'm sure that only happens when he's really reading/writing a ton of data!
