Yes and no. You can mix different size but you would end up with every disk having the same number of bytes which would be the smallest one. You can't add smaller disk afterwards, so add the small disks first.
That's what I understood from the specs of the NAS but never tried.
example :
HDD1=4TO ; HDD2=4TO; HDD3=3TO ==> impossible in Xraid but may be possible in standard raid by having two volumes or maybe in jbod.
HDD1=3To; HDD2=4To; HDD3=4To ==> you will get 6TO in raid 5 (3+3+parity)
HDD1=2To; HDD2=4To; HDD3=4To ==> 4To raid5.
