The ExpressSlot Core MB305M4P-B is a PCIe 4.0 x4 adapter card designed for M.2 NVMe SSDs, featuring a tool-less removable M.2 NVMe SSD tray for seamless drive access and easy maintenance. IT professionals, audio/video editors, and gamers can quickly install or swap M.2 NVMe SSDs without opening the system chassis, making it ideal for servers, industrial PCs, workstations, and media-heavy environments where fast SSD swapping is essential for minimizing downtime, maximizing productivity, or managing media libraries.

Innovative Removable Design for M.2 NVMe SSD

Unlike traditional M.2 NVMe SSD PCIe adapter cards, which require opening the chassis for maintenance, the ExpressSlot Core MB305M4P-B revolutionizes the process with a removable M.2 NVMe SSD tray that can be easily accessed from the PCIe slot panel. This tray allows 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 an ideal solution for enterprise-level systems where time and uptime are critical.

Support 1 x M.2 NVMe SSD & Tool-less SSD Installation

Thanks to the tool-less SSD installation design, installing the M.2 NVMe SSD into the MB305M4P-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 you to install or remove the SSD without unmounting the MB305M4P-B from the PCIe slot.

Optimized Thermal Management

The MB305M4P-B is equipped with an aluminum heatsink lid and an included thermal pad to efficiently dissipate heat from the M.2 NVMe SSD, ensuring stable performance even under intensive PCIe 4.0 workloads. This prevents thermal throttling and maximizes data throughput. The design effectively channels airflow to keep the M.2 NVMe SSD cool, ensuring reliable performance during heavy data transfers.

Superior PCIe 4.0 Performance

The PCIe 4.0 interface delivers unparalleled speed, providing 64Gbps transfer rates-10 times faster than SATA III. This makes the MB305M4P-B an ideal 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 your system future-proof for data-intensive workloads.

Maximum Compatibility for Modern Systems

Designed for PCIe 4.0 x4 slot, the ExpressSlot Core MB305M4P-B is fully compatible with x4, x8, and x16 PCIe slots, offering unmatched flexibility for various system architectures. Whether you're upgrading your server, workstation, or enterprise system, this adapter is engineered to integrate seamlessly.

Packed with Features

The MB305M4P-B comes equipped with drive activity LED indicators, allowing you 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 output (cable not included) allows you to transfer the drive activity signal to the computer case or LED panel and lets you monitor the drive activity in your desired location.
