How does the Dell XPS 8950 improve storage over its predecessor?

The Dell XPS 8950 improves on its predecessor with dual NVMe slots — two M.2 slots running PCIe Gen4 for fast boot and game drives. It also accommodates two 3.5-inch and two 2.5-inch SATA drives through four SATA ports, a noticeable upgrade over the XPS 8930’s single NVMe slot.
