Everywhere you look, people are talking about SSDs (Solid State Drives) and their advantages. You may think that everybody has already replaced their hard drive with an SSD but you. This is far from the truth; what happens is that most memory manufacturers are putting a lot of effort on marketing SSDs basically because their profit margin on regular memory modules has dropped tremendously in the past few years. Add the price drop on memory itself, and SSDs seem to be a good idea for them to make more money. So a lot of people talking about SSDs don't mean that everybody is using SSDs, but that manufacturers are pushing people to talk about them.
