Why are you wanting to use RAID: for speed or redundancy?  To answer your questions, you first need to decide what RAID mode you want to use: 0 or 1.

RAID 0 (sometimes referred to as striping) splits the data between 2 drives, giving you a speed advantage, since it alternates between the two drives when reading or writing.  The size of the RAID 0 array is the sum of the size of the two drives.

RAID 1 (sometimes called mirroring) gives redundancy.  The data is written simultaneously to both drives and can be read from either drive.  It gives a speed increase in reading, but not writing.  Both drives need to be the same size, and while not completely necessary, it's recommended that they both be the same make/model.  The size of the RAID 1 array is the size of a single drive.
