A. You cannot setup Raid 5 with only 2 HDD's, you need a minimum of 3 HDDs to do this.

Usable space with 3x 2gb HDD's would be ~4gb (you loose the total of 1 drive to parity)

with 2TB drives
2x with mirror =1800GB
__________
3x =3600GB
4x =5400GB
~total usable after all waste

3x is not as efficient as 4 as well,
