LORDWORLD NGFF NVME M-Key to Dual Ports Key-M M.2 Adapter ASM1182e

SKU CH-K48S-AAQZD

Converts one M-Key NVME slot into two 2230 NVME ports using an ASM1182e PCIe 2.0 switch for NAS and industrial boards

  • Converts single M-Key slot into two NVME ports
  • ASM1182e packet switch splits one PCIe 2.0 lane into two downstream lanes
  • Accepts only 2230 Key-M NVME SSDs, no B-Key SATA support
  • Both drives operate simultaneously at PCIe x1 Gen2 speed
  • No extra power needed, compact riser preserves original module performance

M-Key NVMe to Dual 2230 Adapter

The LORDWORLD adapter converts a single M-Key NVMe PCIe slot into two M.2 Key-M ports for 2230 form-factor SSDs. It uses an ASM1182e PCIe 2.0 packet switch to split one x1 Gen2 upstream lane into two x1 Gen2 downstream lanes. No extra power is needed and the card does not alter the performance of the installed modules.

Suits NAS and industrial boards needing two 2230

This card fits builders adding a pair of 2230 Key-M NVMe SSDs to a compatible NAS or industrial motherboard with an M-Key PCIe slot. It is not for systems that only provide B-Key SATA M.2 slots or that require full x4 bandwidth per drive. Buyers needing longer M.2 lengths or SATA protocol support should look elsewhere.

Single x1 Gen2 upstream link limits each SSD to x1

The ASM1182e switch connects to the host through one PCIe 2.0 x1 lane, so both SSDs share that single x1 Gen2 bandwidth. This is the deciding specification: if the application demands higher per-drive throughput or PCIe 3.0 and above, this adapter will not meet that requirement.

Questions about this item

How do I install the LORDWORLD NGFF NVME M-Key adapter into my motherboard and what is the common mistake?

Insert the adapter into an M-Key NVME PCI-E slot, then install two 2230 Key-M SSDs into the dual ports; the common mistake is using a B-Key SATA slot or a 2280 drive, which are not supported.

What maintenance or replacement will the ASM1182e adapter need over time?

The adapter itself has no moving parts and requires no scheduled maintenance; only the two 2230 NVME SSDs may need replacement if they reach their write endurance limits.

What performance limit appears first when both SSDs run sustained workloads?

Each SSD operates at PCIe x1 Gen 2.0, so the upstream x1 Gen 2.0 link becomes the bottleneck before the individual drives saturate.
