3 Things to Know About the HP EliteDesk 800 G4 TWR's M.2 Slot

The single M.2 2280 slot supports only NVMe drives over PCIe x4. It does not support SATA M.2 drives, so do not buy a SATA M.2 SSD for this slot.

NVMe drives deliver significantly faster speeds than SATA. This slot is designed for high-performance storage, not compatibility with older SATA standards.

If you need SATA storage, use the HP EliteDesk standard 2.5-inch or 3.5-inch drive bays instead. The M.2 slot is strictly for NVMe, so plan your storage configuration accordingly.
