RAID spreads the files over multiple discs (it will appear as one drive in my computer) either for increased redundancy or increased performance.
Over simplified you get 2 different base flavors of RAID:
Performance version where you get the capacity of both discs, each file's data is spread more or less evenly over both discs so the computer can access 2 bits of the file's data at a time instead of 1 for increased performance but if any one disc fails you lose the lot.
Redundancy version where the capacity will be reduced often to the level of just one disc but the entire contents of each file will be written to every single drive, it will also have a performance gain in read speeds but the main advantage is that if any one disc fails you still have a copy of the file on another disc.
