The Lenovo ThinkCentre M70q Gen 2 caps out at one NVMe SSD and one SATA drive

The M70q Gen 2 keeps things simple with an M.2 2280 slot for NVMe PCIe Gen 3 x4 SSDs and one 2.5-inch SATA III bay. No second SATA port for external drives — you get fast NVMe boot and one bulk storage bay, and that’s the whole picture.
