I guess you can do both if you switch to standard raid, but the default for x-raid2 is to configure them in raid5.
Raid 5 tolerates one failed disk at a time but you get the space of n-1 disks, so with four disk of identical size you get 3*size, the last disk is used for parity. (actually the parity disk should change each time you copy but it's simpler saying one is reserved).
