Partitioning Drives make speed of excess faster?

and what is the RAID option in disk utility for?

I'm not sure quite what you mean, but if you are asking if it will be any quicker having drive with multiple partitions then the answers no.

The RAID option in disk utility would take ages to explain, so here's a link that will explain.

To be fair making a partition on the interior of the drive and then running off of that probably would be slightly faster than accessing it across the whole disk. I don't know if the difference would be noticible.
 
Partitions CAN make a system slightly faster, as was said above. For me, I have increased the speed of my system by creating scratch partitions, so instead of searching for scratch space in applications like CS2 and Cubase, everything is written to a large, blank area. It sped up those apps a bit, but not the system in general...
 
A much more effective method of increasing performance would be to use two hard drives on separate channels (this means no master/slave setup, only master). Put the operating system on one drive, and your applications and home folder on the other.
