With your existing disks, you can configure 1x2tb as parity providing 4TB (2+1+1) of array space with single disk failure tolerance, or 2x2TB as parity giving you 2TB (1+1) of array space as 2 disk failure tolerance (probably a waste when starting out). The larger your parity drive is or the more drives you have in your array, the longer it will take to calculate the parity. drives are 16 times more.
