Choosing at six bays
Protection first. With six drives a rebuild reads five others end to end, so two drives of protection is the usual starting point at this size: 128TB usable from six 32TB drives, against 160TB with one.
The DXP6800 Pro runs on Intel Core i5-1235U with 8GB DDR5, to 64GB.
You do not have to fill it on day one. Buy the drives you need now and add the rest when the space runs short.
