The Minisforum UM790 Pro runs two PCIe 4.0 NVMe SSDs with no SATA bay

The UM790 Pro breaks the typical mini PC pattern by skipping the 2.5-inch SATA bay entirely. Instead, it offers two M.2 2280 slots, both running PCIe 4.0 x4 NVMe. If you’re building a fast all-flash system, this is the more modern approach — just plan for NVMe-only storage.
