Whereas the expandable storage drives with which Microsoft's Xbox Series X and Y will be compatible will be proprietary, the expandable storage drives with which Sony's PlayStation 5 will be compatible will be practically any NVME PCIe Solid State Drive that can fit into its chassis.
Hence, because Microsoft has restricted the Xbox Series X & Y to one type of expandable storage, thereby knowing exactly what form factor their consoles have to accommodate, they didn't have to make either machine larger than they have wound up being. Furthermore, because the required speed of their consoles' expandable storage is only 2.5 GB/s, the form factor of the expandable storage isn't very large, as it doesn't produce much heat and therefore doesn't require a heatsink.
On the other hand, Sony has no way of knowing which expandable storage drives that users of PlayStation 5 will buy and therefore cannot predict exactly how small or large users' choices will be. However, due to the required speed of expandable storage drives for PlayStation 5 being 7 GB/s, Sony can at least assume that they will be on the larger end of the range of sizes possible due to their heat output requiring them to have relatively large heatsinks.
Hence, the PlayStation 5 is as large as it is due to its internal bay for expandable storage drives needing to be large enough to accommodate the largest NVME PCIe Solid State Drives (as well as because it has a robust cooling system to accommodate the heat output of its GPU's top speed of 2.23GHz).
