Silver metal dual-bay PCIe card with two removable M.2 drive trays and key locks

STARTECH

STARTECH 2M2-REMOVABLE-PCIE dual-bay M.2 NVMe to PCIe x8 removable rack

SKU CH-QYRN-JAXWN MPN 2M2-REMOVABLE-PCIE

Dual-bay removable rack lets you hot-swap two M.2 NVMe SSDs via a PCIe x8 slot

  • Dual M.2 NVMe drives install tool-less into hot-swap trays
  • PCIe x8 host interface delivers full NVMe bandwidth to both bays
  • Removable trays let you swap SSDs without opening the case
  • Locking keys secure each drive against unauthorised removal
  • Bifurcation-ready backplane splits one x8 slot into two x4 NVMe paths

Dual-Bay Removable M.2 NVMe Rack

This PCIe x8 adapter fits two M.2 NVMe drives in removable trays for tool-less swaps. It targets builders who need quick access to high-speed storage without opening the case. The unit mounts in a standard full-height slot and includes keys for physical drive security.

Bifurcation and Lane Requirements

The adapter needs a platform that supports PCIe bifurcation to split the x8 link into two x4 paths. Without that support the second drive will not be detected by the system. It carries no onboard controller, so drive visibility depends entirely on the host CPU or chipset lane allocation.

Replaces Fixed Internal M.2 Slots

This rack replaces soldered M.2 sockets when drives must be rotated between machines or taken off-site. The jump is worth it for workflows that move multi-terabyte datasets daily and cannot tolerate downtime for chassis disassembly. It does not serve builds that lack bifurcation or only need a single permanent drive.

Questions about this item

Should I choose the single-bay or dual-bay version of this adapter?

This product is the dual-bay version only, providing two removable M.2 NVMe drive trays in a single PCIe x8 add-in card.

What does the PCIe x8 specification mean for my installed M.2 NVMe drives?

The x8 electrical connection splits into two x4 lanes, so each M.2 NVMe SSD can run at its full PCIe 3.0 x4 or 4.0 x4 speed, provided the host platform supports bifurcation.

Does this rack require PCIe bifurcation and what happens without it?

Yes, bifurcation is required; without it the motherboard will only recognise the first drive, leaving the second bay inaccessible.
