3.5 inch or 2.5 inch hard drive?

3.5 inch for desktops, NAS, recorders and servers, where capacity per drive matters and there is room; 2.5 inch for laptops and for the dense server bays built for it. The larger platters of a 3.5 inch drive carry far more data per drive; the 2.5 inch draws less power and takes less space. The bay decides it, so check the enclosure before the drive.
