I'm going to buy a new laptop sometime soon and I just had a quick question about laptop hard drive speeds. I plan on buying a Toshiba Satellite M35x S161 laptop off my friend and I noticed the hard drive speed is 4200RPM. I'm a student and no gaming will be done on this thing, I plan mainly on using this thing for storing media (music and movies), surfing the web, and using MS Word. Now, what I want to know, should I upgrade the hard drive to a faster speed? IE buy a faster hard drive off the company and swap it with the old hard drive. Or for my uses is the 4200RPM good enough?
