Eight bays is the size where two drives of protection cost a quarter of the array and still leave six drives of space.

Choosing at eight bays
Protection first. With eight drives a rebuild reads seven others end to end, so two drives of protection is the usual starting point at this size: 192TB usable from eight 32TB drives, against 224TB with one.
Then the difference between the models: the DXP8800 Plus runs on Intel Core i5-1235U with 8GB DDR5, to 64GB, and the DS1825+ runs on AMD Ryzen V1500B with 8GB DDR4, to 32GB.
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.
