Transform Your PCIe Slot into a High-Speed Removable M.2 NVMe SSD Bay

The ExpressSlot Elite MB840M5P-B by ICY DOCK redefines storage flexibility by converting a standard PCIe 4x, 8x, or 16x expansion slot into a hot-swappable M.2 NVMe SSD bay. This innovative solution enables users to quickly install or replace SSDs without opening the computer case, streamlining storage management for professionals and enthusiasts alike.

Unmatched PCIe 5.0 Performance

Engineered for the latest PCIe 5.0 standard, the MB840M5P-B delivers ultra-fast data transfer speeds up to 128 Gbps—twice the bandwidth of PCIe 4.0 and over 20 times faster than traditional SATA connections. Compatible with PCIe 5.0, 4.0, and 3.0 x8/x16 slots, this NVMe SSD enclosure is ideal for enterprise workstations, high-performance computing, AI development, and data-intensive applications. Direct PCIe connectivity eliminates bottlenecks and cable clutter, ensuring low-latency, high-throughput storage for demanding workloads.

Effortless, Tool-less SSD Installation

Traditional M.2 SSD installation often involves fiddly screws and direct motherboard access. The MB840M5P-B simplifies this process with a removable drive tray and a tool-less design, allowing users to install or swap M.2 NVMe SSDs in under five seconds. The tray supports all standard M.2 sizes—2230, 2242, 2260, 2280, and 22110—ensuring broad compatibility with current and future SSDs.

Advanced Thermal Management

Maintaining optimal SSD temperatures is crucial for sustained performance. The MB840M5P-B features an aluminum drive tray that acts as an integrated heatsink, efficiently dissipating heat from the SSD. An included thermal pad ensures maximum contact between the SSD and the enclosure, while the open design promotes airflow for effective cooling during intensive operations.

Flexible Installation for Any System

The MB840M5P-B comes with interchangeable full-height and half-height PCIe brackets, making it suitable for both standard desktops and low-profile systems. This flexibility allows seamless integration into a wide range of workstation and server environments.

Reliable EMI Grounding and SSD Protection

Frequent SSD swaps can expose drives to electrostatic discharge (ESD) risks. The MB840M5P-B incorporates EMI grounding technology, automatically grounding the SSD as soon as it is secured in the tray. This feature provides continuous protection against electrical damage, ensuring data integrity and drive longevity.

Optimized for High-Performance Applications

Designed to maximize the capabilities of PCIe 5.0, 4.0, and 3.0 x8/x16 slots, the MB840M5P-B is perfect for high-bandwidth tasks such as 4K/8K video editing, AI and machine learning workloads, and scientific computing. Its ultra-fast 128 Gbps transfer rate supports seamless handling of uncompressed video, rapid data analysis, and efficient scaling in cloud computing environments.

Industrial-Grade Durability

Built for reliability, the MB840M5P-B features a rugged all-metal construction, including the chassis, drive tray, and mounting bracket. Integrated anti-vibration technology protects SSDs from shock and external impacts, making it suitable for demanding industrial and enterprise settings.

Intelligent Power and Activity Monitoring

The MB840M5P-B is equipped with a drive activity LED indicator on the tray, providing real-time status updates. The LED automatically powers off when no drive is present to conserve energy. An optional 2-pin HDD activity signal output allows users to route drive activity signals to a case or external LED panel for enhanced monitoring.

Seamless Compatibility Across Platforms

Unlike conventional M.2 SSD enclosures, the MB840M5P-B connects directly to the PCIe bus, eliminating the need for extra power or data cables. It is fully compatible with all PCIe expansion slots, including those found in the 2019 and newer Mac Pro, offering a cost-effective alternative to proprietary storage solutions.

Versatile Removable Drive Tray

The MB840TP-B removable drive tray is designed for effortless interchangeability across multiple compatible models, further enhancing workflow efficiency and storage flexibility.

Looking for a 2.5" SATA SSD Solution?

For users needing to install a 2.5" SATA SSD via a PCIe slot, the ExpressSlot Elite MB839SP-B offers hot-swap capability and compatibility with PCIe 2.0 slots or higher. Pair it with the EZConvert MB703M2P-B M.2 SATA to 2.5" SATA adapter to easily swap between M.2 SATA SSDs and 2.5" drives within the same receiver frame.
