@entrana..
I am not very conversant with the RAID architecture...as far as I know, if u set up your HDD in a RAID architecture, the system treats it as one single drive, and data is transferred simultaneously to both drives. This means, theoretically, your HDD data transfer rate doubles in speed.
But, it'll be great if someone can second this definition.
