The ASRock DeskMini B660 adds a PCIe 4.0 NVMe slot to the DeskMini family

The ASRock DeskMini B660 brings two M.2 NVMe slots — one at PCIe 4.0 x4, one at PCIe 3.0 x4 — alongside the usual 2.5-inch SATA bay. The Gen 4 slot is the headline here, doubling bandwidth for compatible SSDs over the older DeskMini models. If you want fast NVMe storage in a tiny chassis, this is ASRock’s best option.
