OK I know most reviews say the SSD is not worth the extra money. But, when I worked on my friends SSD I must say it just feels faster in normal use. I also know this from my previous laptop where I had SSD. So I'd like to know: are there SSD's out there that we can buy and install ourselves? Which ones and how much do they cost? I believe it needs to be 1,8 inch with Ziff connection... right?
