I'm currently searching for a good boot drive for a desktop. Is heat an issue for an SSD?
I don't know if SSD produce less heat. Not according to this: http://benchmarkreviews.com/index.php?option=com_content&task=view&id=299&Itemid=60&limit=1&limitstart=11
But remember these are 2.5" SSD. I bet 3.5" HDD would produce more heat.
Yup, according to this: http://www.codinghorror.com/blog/archives/000748.html
3.5" HDD produce a lot more heat. So if you are using SSD on the desktop, you don't even need a fan on it.
