I think 4TB is the largest sata drive? They are about A$1600 here. So to to fill this box I'd be looking at just under A$21,000 (given the box itself will probably retail for about A$1500), for 48TB of space. 4 x 12TB HDDs will set me back about A$1900. Would I pay $21000 for 48TB Storage. Not a chance.
