Id like a new ssd for the simple fact that I have a 60gb boot ssd and a 200gb wd 2.5 laptop hdd in my current desktop. Its all hand-me downs and id like to actually have a new part in my pc. As for why everyone should use ssd's, the answer is clear. Better performance and survivability as opposed to its mechanical brother. Not to mention it takes up less space in a pc and runs silent.
