dude...
no...
a loving PETABYTE
a petabyte = 1,024TB
That only exists in storage racks of hard drives, i.e. LOTS and LOTS of TB HDDs. Plus what the forget would a single person do with a petabyte? I don't have that much stuff.
I'd buy an 80GB SSD for Windows, 1TB for Games, 1TB for pictures, music and movies, and 1TB for FRAPS recording and other such.
