  • Holds two M.2 NVMe SSDs from 30 to 110 mm
  • PCIe 4.0 x8 slot supports up to 16 GT/s per lane
  • Tool-less removable trays let you swap drives without a screwdriver
  • Eagle-hook lock secures each SSD inside the tray
  • Single-width full-height card fits standard PCIe expansion slots

Dual M.2 NVMe adapter card

The ICY DOCK ExpressSlot MB842MP-B fits two M.2 PCIe NVMe SSDs ranging from 30 to 110 millimetres. It installs in a single-width full-height PCIe slot and uses tool-less removable trays with an eagle-hook lock for drive security.

Requires PCIe bifurcation

Both drives are accessible only when the host platform provides PCIe bifurcation at x4, x4, x4, x4 for a sixteen-lane slot or x4, x4 for an eight-lane slot. Without this motherboard feature the second drive will not be detected.

Sustained throughput depends on host lanes

Under continuous workloads the adapter delivers the bandwidth of the allocated PCIe 3.0 or 4.0 lanes. Thermal performance relies on case airflow because the card has no active cooling of its own.

Questions about this item

Will both M.2 NVMe SSDs run at full speed inside my computer?

Both drives operate at PCIe 4.0 x4 each when the host slot supports PCIe bifurcation into x4, x4 lanes.

Does this card need PCIe bifurcation to see both drives?

Yes, the motherboard must split an x8 or x16 slot into two x4 links; without bifurcation only one drive will be detected.

What length M.2 NVMe SSDs fit in the removable trays?

The trays accept 2230, 2243, 2260, 2280 and 22110 form factors, covering lengths from 30 mm to 110 mm.
