ICYDOCK MB312M4P-B ExpressSlot Core

Removable double M.2 NVMe SSD - PCIe 4.0 x8 mobile rack adapter card for PCIe expansion slot.

The ExpressSlot Core MB312M4P-B is a PCIe 4.0 x8 adapter card designed to support two M.2 NVMe SSDs and features a tool-free M.2 NVMe SSD tray for seamless drive access and easy maintenance. IT professionals, audio/video editors, and gamers can quickly install or replace two M.2 NVMe SSDs without opening the system case, making them ideal for servers, industrial PCs, workstations, and media-intensive environments where fast SSD replacement is essential to minimize downtime, maximize productivity, or manage media libraries.

*Please note that this product requires a motherboard with PCIe Bifurcation mode to recognize both M.2 NVMe SSDs.

Unlike traditional M.2 NVMe SSD PCIe adapter cards that require opening the case for maintenance, the ExpressSlot Core MB312M4P-B revolutionizes the process with dual removable M.2 NVMe SSD trays. These trays are easily accessible from the PCIe slot panel for quick and tool-free access, perfect for tasks such as data backup, system recovery or daily operations in demanding environments. Because the entire adapter card does not need to be removed, it is an ideal solution for enterprise-grade systems where time and uptime are critical.

Tool-less SSD installation makes installing M.2 NVMe SSDs in the MB312M4P-B easier than ever. First, place the M.2 SSD retaining clip into the semicircular notch above the screw hole, then place both the M.2 NVMe SSD and the retaining clip on the tray. Then install the thermal pad and reattach the heatsink cover to complete the installation. The entire process takes less than 60 seconds, so SSDs can be installed or removed without disconnecting the MB312M4P-B from the PCIe slot.

The MB312M4P-B is equipped with an aluminum heatsink cover and cooling pads to effectively dissipate heat from the dual M.2 NVMe SSDs, ensuring stable performance even under intense PCIe 4.0 loads. This prevents thermal throttling and maximizes data transfer. The design effectively channels airflow, keeping both M.2 NVMe SSDs cool and providing reliable performance during high-volume data transfers.

The PCIe 4.0 x8 interface offers unparalleled speed, providing a transfer rate of 64 Gbps - ten times faster than SATA III. This makes the MB312M4P-B an ideal solution for applications that require high-speed data transfer, such as artificial intelligence, big data analysis and cloud computing. Experience reduced latency and faster data access with PCIe 4.0, making your system future-proof for data-intensive workloads.

Designed for the PCIe 4.0 x8 slot, the ExpressSlot Core MB312M4P-B is fully compatible with both x8 and x16 PCIe slots, offering unparalleled flexibility for a variety of system architectures. Whether you're upgrading a server, workstation, or enterprise system, this adapter is designed for seamless integration.

The MB312M4P-B is equipped with dual drive activity indicators that allow you to check SSD performance and activity at a glance. The auto-shutdown feature further improves energy efficiency by shutting down the device when no SSD is detected.

The optional 2-pin HDD activity signal outputs (cable not included) allow the drive activity signal to be transmitted to the computer case or LED panel, and enable monitoring of the drive activity at the desired location.
