The ASRock DeskMini X300 favors SATA bulk storage over a second NVMe slot

The ASRock DeskMini X300 takes a different approach to storage — one M.2 NVMe slot (PCIe 3.0 x4) paired with two SATA 6Gb/s ports for 2.5-inch drives. The chassis holds up to two 7mm-thick drives in a single bay, which is unusual for such a small system. If SATA bulk storage matters more than a second NVMe slot, this layout wins.
