Icy Dock ExpressSlot Core MB312M4P-B PCIe 4.0 x8 Adapter Card for 2xM.2 NVMe SSDs

Icy Dock introduces the ExpressSlot Core MB312M4P-B a PCIe 4.0 x8 adapter card designed to support ^(*⁾ 2xM.2 NVMe SSDs, featuring a tool-less removable M.2 NVMe SSD tray for drive access and easy maintenance.

IT professionals, audio/video editors, and gamers can quickly install or swap 2xM.2 NVMe SSDs without opening the system chassis, making it for servers, industrial PCs, workstations, and media-heavy environments where fast SSD swapping is essential for minimizing downtime, maximizing productivity, or managing media libraries.

^(*) Note that this product requires a motherboard with PCIe Bifurcation mode to recognize both M.2 NVMe SSDs.

Removable Design for M.2 NVMe SSD

Unlike traditional M.2 NVMe SSD PCIe adapter cards that require opening the chassis for maintenance, the ExpressSlot Core MB312M4P-B revolutionizes the process with dual removable M.2 NVMe SSD trays. These trays can be easily accessed from the PCIe slot panel, allowing quick and tool-less access, perfect for tasks like data backup, system recovery, or daily operations in demanding environments. With no need to remove the entire adapter card, it’s a solution for enterprise-level systems where time and uptime are critical.

Support 2xM.2 NVMe SSD and Tool-less SSD Installation Thanks to the tool-less SSD installation design, installing the M.2 NVMe SSDs into the MB312M4P-B has never been easier. First, position the M.2 SSD mounting clip into the semi-circular notch above the screw hole, then place both the M.2 NVMe SSD and the mounting clip onto the tray. Next, apply the thermal pad and reattach the heatsink lid to complete the installation. The entire process takes less than 60 seconds, allowing user to install or remove the SSDs without unmounting the MB312M4P-B from the PCIe slot.

Optimized Thermal Management

The MB312M4P-B is equipped with aluminum heatsink lids and included thermal pads to efficiently dissipate heat from the dual M.2 NVMe SSDs, ensuring stable performance even under intensive PCIe 4.0 workloads. This prevents thermal throttling and maximizes data throughput. The design effectively channels airflow, keeping both M.2 NVMe SSDs cool and ensuring reliable performance during heavy data transfers.

PCIe 4.0 Performance

The PCIe 4.0 x8 interface delivers unparalleled speed, providing 64Gb transfer rates – 10 times faster than SATA 3. This makes the MB312M4P-B a solution for applications that demand high-speed data transfer, such as AI, big data analytics, and cloud computing. With PCIe 4.0, you’ll experience reduced latency and faster data access, making user’ system future-proof for data-intensive workloads.

Maximum Compatibility for Modern Systems

Designed for PCIe 4.0 x8 slot, the ExpressSlot Core MB312M4P-B is fully compatible with x8 and x16 PCIe slots, offering unmatched flexibility for various system architectures. Whether you’re upgrading server, workstation, or enterprise system, this adapter is engineered to integrate seamlessly.

Packed with Features

The MB312M4P-B comes equipped with dual drive activity LED indicators, allowing user to monitor SSD power and activity at a glance. The auto-power-off feature further enhances energy efficiency by shutting down the device when no SSD is detected. The optional 2-pin HDD activity signal outputs (cable not included) allow user to transfer the drive activity signal to the computer case or LED panel and lets monitor the drive activities in your desired location.
