NasBoost CP2M Expansion Card | PCIe to M.2 NVMe x 2 Ports | 2x 32Gbps | Dual-Slot Bifurcation Card
Upgrade your homelab, DIY NAS, or server storage topology with the NasBoost CP2M PCIe X8 to M.2 NVMe x 2 Ports expansion card. This high-performance passive adapter splits a single PCIe X8 slot into two independent M.2 NVMe slots (M-Key), allowing you to run two high-speed SSDs concurrently at full bandwidth up to 2x 32Gbps. Featuring an ultra-compact low-profile PCB design, it is tailored perfectly to slide into tight 2U server rackmounts or slim compact NAS chassis without blocking airflow.
Key Features
- Dual-Slot Full Speed Storage Expansion: Bridges your PCIe X8 hardware interface to dual M.2 NVMe ports, delivering dedicated full-channel performance for software RAID arrays or fast caching tiers.
- Enterprise 22110 Compatibility: Fully supports various SSD form factors including consumer-grade 2230, 2242, 2260, 2280, and large-capacity 22110 enterprise-grade NVMe SSDs.
- Flexible PCIe Slot Matching: Designed natively for PCIe X8 slots, but physically compatible with full-sized PCIe X16 slots, giving you maximum deployment flexibility on your motherboard.
- Thickened Gold Fingers & Signal Integrity: Equipped with heavily gold-plated connectors for anti-oxidation, extreme durability, and lossless high-frequency signal transmission.
- Integrated Diagnostic Soft-LEDs: Onboard soft-glow status indicators stay solid during standby and flash gracefully during data read/write processes for effortless drive health tracking.

⚠️ CRITICAL REQUIREMENT: Motherboard PCIe Bifurcation Required
Please check your hardware compatibility before ordering. This is a passive expansion adapter without an onboard PLX bridge chip:
- BIOS Bifurcation Mode: Your motherboard BIOS MUST support PCIe Lane Bifurcation on the target slot. You must configure the slot setting to X4X4 or 4X4 mode. If your motherboard does not support bifurcation, ONLY ONE SSD will be recognized by the system.
- Software RAID Only: This card supports OS-level software RAID configurations (such as Windows Storage Spaces, Linux mdadm, or Unraid/TrueNAS pool management). It does not contain a hardware RAID controller chip.
