One thing I forgot to include in the video is how the capacity of the RAID-array is calculated. The total capacity of the array is: (n x cs) - cs = tc n = number of drives cs= capacity of the smallest drive tc = total capacity So if you have 3 drives, and they are 2x500GB and 1x750GB the total capacity will be: (3 x 500) - 500 = 1000GB So the optimal RAID 5 array is formed with drives of the same size.
