NasBoost CP4M-P Expansion Card | PCIe to M.2 NVMe x 4 Ports | 4x 32Gbps | Double-Sided Bifurcation Card
Take your homelab or enterprise storage to the next level with the NasBoost CP4M-P Double-Sided PCIe to M.2 NVMe x 4 Ports expansion card. Unlike traditional single-sided cards, the CP4M-P features an innovative dual-sided layout (2 slots on the front, 2 on the back) and a slim form factor, making it fully compatible with 2U servers and low-profile chassis. Equipped with an integrated premium blower fan and an upgraded hardware architecture, it delivers maximum full-speed signal up to 4x 32Gbps simultaneously without thermal throttling.
Key Features
- Innovative Double-Sided Layout: Splits 4 x M.2 slots evenly across both sides (2 front, 2 back) to optimize space and ensure excellent heat dissipation.
- Active Blower Fan with 2-Speed Switch: Features a high-quality active turbine fan with a physical toggle. Switch to LOW (Green LED) for whisper-quiet daily NAS operation, or HIGH (Blue LED) for heavy data center workloads.
- Extended 22110 Enterprise SSD Support: Accommodates not only consumer 2242, 2260, and 2280 drives but also high-capacity 22110 enterprise-grade NVMe SSDs.
- 2U Server & Slim Chassis Friendly: Includes both Full-Height and Half-Height (Low-Profile) brackets, making it the perfect upgrade for space-constrained rackmount servers or custom DIY NAS enclosures.
- Smart LED Status Indicators: On-board soft-light LEDs stay solid when powered on and flash gently during data read/write cycles for quick array troubleshooting.

⚠️ CRITICAL CRITERIA: Motherboard PCIe Bifurcation Required
Please read carefully before purchasing. This is a passive expansion card that does NOT contain an onboard PLX bridge chip. Recognition of 4 drives depends entirely on your system topology:
- Motherboard Bios Support: Your motherboard MUST support PCIe Lane Bifurcation. You must be able to change your Bios setting for the target slot to X4X4X4X4 or 4X4X4X4 mode. If your BIOS only supports X8+X4+X4, it will only detect 3 drives. Without bifurcation support, ONLY ONE drive will be recognized.
- CPU Lane Constraints: Ensure your CPU has enough dedicated PCIe lanes available. Low-end or budget CPUs lack the required lanes to split a full X16 slot into quad-X4 pathways.
- PCIe Lane Sharing: Many motherboards share bandwidth across slots. If your card fails to recognize all 4 drives despite enabling bifurcation, try removing or relocating other high-bandwidth devices (such as discrete GPUs, other expansion cards, or onboard NVMe arrays).
