This is a Press Release edited by StorageNewsletter.com on October 17, 2025 at 2:01 pmIcy Dock launches the ExpressSlot Elite MB840M5P-B adapter to transforms a PCIe 4x, 8x, or 16x expansion slot into a removable M.2 NVMe SSD bay, allowing for quick and easy SSD swaps without the need to open computer case.
Cutting-Edge PCIe 5.0 Compatibility
The MB840M5P-B is designed to leverage the power of PCIe 5.0, offering blazing-fast 128Gb transfer speeds – double the bandwidth of PCIe 4.0 (64Gb) and over 20x faster than SATA (6Gb). Engineered for PCIe 5.0, 4.0, and 3.0 x8/x16 slots, this high-speed NVMe solution ensures maximum flexibility across enterprise workstations, HPC, AI training, and data-intensive applications. By utilizing direct PCIe connectivity, it eliminates bottlenecks, reduces cable clutter, and delivers ultra-low latency storage performance for next-gen workloads.
Effortless M.2 NVMe SSD Management
Traditional M.2 SSD installation requires mounting the drive onto the motherboard or a riser card, secured with a small screw – often a cumbersome and time-consuming process. The MB840M5P-B simplifies this by utilizing the PCIe expansion slot, making M.2 SSD installation and removal quick and hassle-free with its removable drive tray design.
Quick and Tool-less SSD Installation
With the firm’s tool-less design, installing or replacing an M.2 NVMe SSD takes less than 5 seconds, eliminating the frustration of handling small screws. This cutting-edge mechanism ensures a workflow for drive maintenance.
The removable M.2 NVMe SSD tray (MB840TP-B) supports standard M.2 sizes, including 2230, 2242, 2260, 2280, and 22110, ensuring maximum SSD compatibility.
Superior Cooling for Maximum Performance
Designed with heat dissipation in mind, the MB840M5P-B’s aluminum tray acts as a built-in heatsink, efficiently transferring heat away from the SSD.
The included thermal pad fills any gaps between the SSD and the metal enclosure, ensuring optimal contact and efficient heat transfer. This design allows airflow to dissipate heat more effectively, maintaining peak SSD performance.
Flexible Installation with Full and Half-Height Brackets
The MB840M5P-B features a swappable PCIe slot bracket, supporting both full-height and half-height system configurations.
- Use the half-height bracket for low-profile builds.
- Use the full-height bracket for standard desktop installations.
- Adapt to any system requirement with ease.
Reliable EMI Grounding for SSD Protection
Frequent SSD swapping introduces the risk of electrostatic discharge (ESD) damage. The MB840M5P-B prevents this with built-in EMI grounding technology. With our tool-less adjustable M.2 locker, the moment the SSD is secured in place, it is automatically grounded, ensuring continuous protection against electrical damage.
High-Speed Data Transfer
The MB840M5P-B is engineered to fully utilize PCIe 5.0, 4.0, and 3.0 x8 and x16 slots, ensuring broad compatibility across various enterprise and high-performance computing platforms. With ultra-fast 128Gb data transfer speeds, this cutting-edge storage solution is built for demanding applications such as 4K/8K video processing, where handling of uncompressed video footage is essential. It also excels in AI and machine learning workloads, providing the necessary high-speed data throughput for deep learning models and real-time inference processing. Additionally, the MB840M5P-B enhances high-performance cloud computing, allowing for rapid VM storage scaling and maximizing data center efficiency. For research professionals and data analysts, this PCIe 5.0-enabled solution accelerates scientific computing and data mining operations, ensuring faster simulations and efficient handling of massive datasets.
Rugged All-Metal Build for Industrial Reliability
Designed to withstand harsh environments, the MB840M5P-B features a full-metal construction including the chassis, drive tray, and mounting bracket. An anti-vibration mechanism is integrated into the enclosure, protecting the SSD from shock and external damage.
Built-in Power and Activity Indicators
The MB840M5P-B is equipped with drive activity LED indicator on the tray that shows the drive power and activity. The LED will be automatically powered off when no drive is installed to save power.
The optional 2-pin HDD activity signal output (cable not included) allows user to transfer the drive activity signal to the computer case or LED panel and lets user monitor the drive activity in the desired location.
Compatibility with All PCIe Expansion Slots (Including 2019+ Mac Pro)
Unlike traditional M.2 SSD enclosures, the MB840M5P-B operates through a direct PCIe connection, eliminating unnecessary power or data cables. Mac Pro (2019+) users can also benefit from PCIe-based SSD storage expansion at a fraction of the cost compared to Apple’s proprietary storage solutions.
Wide Range of Compatibility
Specially designed MB840TP-B removable drive tray effortlessly enables interchangeability across various models.
