You're absolutely wrong. Having a 500gb hard drive full of videos creates a slower-performing system than having a 500gb hard drive with 400gb available. See my above reference. Not sure what people's obsession with storing things is... why would you carry all your movies with you slowing down your drive when you can have one massive drive at home (hell you can even have a server to access when on the road),.... but for 99.999% of people web surfing, documents, email, spreadsheets, and presentations, oh, and games, is the function of their laptop... so how many movies do you need? At 700mb per movie, you could watch 300 movies every trip with a loaded 256 SSD... but I'd be willing to bet you don't watch but 1 or 2 movies... so why carry them all? The american way - if I don't need it, store it... lol...self-storage companies make a killing doing exactly what you're mentality creates, hah
