Whenever I see people building their own pc, I see a lot of them buy two disc drives, why is this?

Actually I have 6 hard disks in my PC. My boot (operating system, plus programs) disk is actually two disks. They are configured as RAID 0. Why? Because using two disks in this configuration increases the hard disk performance by up to two times.
My data (documents, digital pictures, etc) disk(s) are configured as RAID 1. This configuration is slightly different. In this setup whatever gets written to one disk is also written on the second disk. RAID 1 configuration does not increase hard disk performance but it is double safe!
Another reason why people use more than one disk is when they upgrade to a larger disk, they don't trash their older disk. It's still usable as extra breathing space, also useful for backing up disks or files.

Many have personal reasons. Some may use one drive to install and run progams from, while the other stores files.
Other reasons may include things like as operating systems get upgraded, some, older software may not run on the new one. Two hard drives may allow a user to but up one O.S. to run older applications, and another O.S. to run the newer ones.
Before hard drive came down in price, some users "partitioned" the hard drive, for similar reasons.
