Depends on the kind of RAID. Some kinds of RAID increase redundancy by putting the data in 2 or more different drives so if one drive fails the other will still have it. Other kinds increase speed by putting your data on 2 or more different drives, so if you need to get a file and half is on one drive and half is on the other it can get that file twice as fast (not really twice, but that's the idea). Other forms of RAID try to combine the two things (redundancy and speed) in various ways to improve both to varying degrees.

In the case above they're doing RAID 0 which splits the data between 2 or more drives to increase the speed by using multiple drives simultaneously.
