## Summary description

The icy dock MB312M4P-B is an adapter card that fits two M.2 NVMe SSDs and connects to a PCIe 4.0 x8 slot using bifurcation. It enables the installation of dual M.2 drives in systems that support PCIe lane splitting, offering high-speed NVMe storage expansion for desktops and workstations. Ideal for users adding fast local storage for editing, virtualization, or caching.

## Long description

The icy dock MB312M4P-B is an adapter card designed to install two M.2 NVMe SSDs into a single PCIe 4.0 x8 slot using PCIe bifurcation. It provides a compact solution for adding high-speed NVMe storage to desktops and workstations that support lane splitting, enabling the use of two separate NVMe devices through one physical PCIe connection. The card is intended to extend local storage capacity and performance for tasks that benefit from fast, low-latency SSD access.
Advantages
The adapter supports PCIe 4.0 x8 host connectivity and leverages PCIe bifurcation to present two independent M.2 NVMe drives to the system, allowing near-native NVMe performance for each installed SSD. Its compact form factor simplifies installation in standard PCIe slots without requiring separate cables or external enclosures. The design provides a practical path to expand high-speed local storage while maintaining direct motherboard-level NVMe access.
Suitable for
Expanding local NVMe capacity in desktops and workstations
Video editing and content creation systems requiring fast scratch or project drives
Virtualization hosts needing multiple fast boot or data drives
Caching and tiering setups where separate NVMe devices are used for performance layers
Key specifications
Host interface: PCIe 4.0 x8 (requires motherboard support for bifurcation)
Drive interface: 2 × M.2 NVMe SSD slots (M.2 form factor)
Supported drive types: NVMe (PCIe) M.2 SSDs
Form factor: PCIe adapter card designed for internal installation
Drive count: two M.2 NVMe SSDs
How to use
Install the adapter card into an available PCIe 4.0 x8 slot on a compatible motherboard that supports PCIe lane bifurcation. Insert M.2 NVMe SSDs into the two M.2 slots and secure them according to the card's mounting points. Configure PCIe bifurcation in the system BIOS/UEFI if required so the host presents the two M.2 devices independently. After installation and BIOS configuration, install operating system drivers or storage management software as needed to recognize and use each NVMe drive.
Usage recommendations
Verify that your motherboard BIOS/UEFI supports PCIe bifurcation and that the chosen PCIe slot provides x8 lanes at PCIe 4.0. Use compatible NVMe M.2 SSDs and confirm thermal clearance and airflow within the chassis to maintain drive performance. For workloads demanding maximum sustained performance, ensure adequate cooling for both the adapter area and the M.2 drives.
