ICY DOCK MB309A M.2 NVMe PCIe 4.0 x4 to SlimSAS 4i Adapter

Connect an M-key M.2 NVMe SSD to a host SlimSAS 4i connection without placing the drive directly on a motherboard M.2 socket. This ICY DOCK adapter carries a PCIe 4.0 x4 NVMe connection through its SlimSAS 4i interface, providing a practical way to position an M.2 SSD at an available PCIe expansion opening. MB309A accepts common M-key M.2 NVMe form factors: 2230, 2242, 2260 and 2280. The SSD mounts on the adapter board, while the SlimSAS 4i connection routes PCIe lanes to a compatible host-side SlimSAS connection. This arrangement suits servers and workstations where an internal SlimSAS PCIe connection is available but direct motherboard M.2 placement is constrained by board layout, cooling hardware, or physical access. The PCIe bracket form factor distinguishes this adapter from internal M.2 mounting arrangements that remain on the motherboard surface. It uses the expansion-slot opening for mechanical placement rather than converting the NVMe drive into a different storage protocol. Match the adapter to an M-key NVMe SSD, a compatible SlimSAS 4i PCIe host connection, and appropriate SlimSAS cabling for the system layout.
