The docking station supports M.2 NVMe SSDs with M-Key or M+B Key, which means that it is suitable for the Samsung 990 EVO Plus NVMe M.2 SSD, as this also has an M-Key interface. However, the docking station does not support the full bandwidth of PCIe 4.0x4, as it offers a maximum of 20 Gbps via USB 3.2 Gen 2.
