Dell XPS 8950 vs XPS 8930: Dual NVMe slots make the 8950 a clear upgrade for storage speed

The XPS 8950 doubles down with two PCIe Gen4 NVMe slots, while the 8930 only had one. That means faster boot and game drives, plus the 8950 still keeps four SATA ports for two 3.5-inch and two 2.5-inch drives. If you need more NVMe storage, the 8950 is the better pick.
