performance as well as data storage efficiency. The disk array data capacity is equal to the number of members times the
performance as well as data storage efficiency. The disk array data capacity is equal to the number of members times the
smallest member capacity. For example, one 40GB and one 60GB drives will form an 80GB (40GBx2) disk array.
