Dual-sided PCIe x16 card with four M.2 NVMe slots

SMUGDESK

SMUGDESK PH44PRO Dual-Sided 4-Port M.2 NVMe PCIe x16 Splitter

SKU CH-70R5-405GS

A dual-sided PCIe x16 splitter card adds four independent M.2 NVMe ports, each running at up to 32Gbps, and supports 2242, 2260, 2280 and 22110 SSDs for high-density RAID arrays in 2U servers

  • Expands one PCIe x16 slot into four independent M.2 NVMe ports
  • Each channel delivers up to 32 Gbps bandwidth for parallel multi‑disk operation
  • Supports 2242, 2260, 2280 and 22110 form‑factor NVMe SSDs
  • Dual‑sided layout fits 2U rackmount servers for high‑density RAID arrays
  • Industrial‑grade signal integrity and heat dissipation for sustained heavy‑load server use

PCIe x16 to 4× M.2 NVMe Splitter

The SMUGDESK PH44PRO converts a single PCIe x16 slot into four independent M.2 M-Key NVMe ports using a dual-sided layout. Each channel operates at up to 32Gbps bandwidth for multi-drive parallel performance. It accepts 2242, 2260, 2280 and 22110 form factors. The card targets 2U rackmount servers and high-density storage arrays.

2U Server RAID Expansion

Suited for administrators building high-capacity NVMe RAID arrays inside space-constrained 2U chassis. Not suited for platforms without a PCIe x16 slot or for drives exceeding the listed M.2 lengths. Builders needing more than four NVMe devices per slot should evaluate alternative expansion topologies.

Four Lanes at 32Gbps Each

The decisive specification is the 32Gbps per-channel bandwidth delivered across four simultaneous NVMe links. This throughput ceiling determines whether the adapter saturates the attached SSDs under heavy multi-disk workloads. Verify the host platform can supply a full x16 link to realise the stated per-port performance.
