People are more commonly using a small-capacity drive for the OS and programs, while using large-capacity drives for media such as games and music.
I personally just use a 640GB Western Digital Caviar Black for my OS, programs and many games. The rest of my media is stored on other Caviar Black drives with 1TB capacity.
The better 7200RPM drives these days perform very well and are built for exceptional reliability. For tasks like gaming, I wouldn't bother getting a VelociRaptor over something like a Caviar Black if you are not using a RAID-0 array.
