Icy Dock ToughArmor EX MB601V4KW-B Ruggedized 1-Bay 2.5-Inch U.2/U.3 NVMe SSD Mobile Rack

Icy Dock unveils the ToughArmor EX MB601V4KW-B features a Tough-Cover IPX6-rated water-resistant front panel, providing protection against dust, splashes, and harsh environmental elements.

Designed for military, field, and edge applications, this rugged enclosure supports 1×2.5” U.2/U.3 NVMe SSD (up to 15mm height) and fits into a standard external 3.5″ drive bay – ideal for deployments where durability, mobility, and reliability are essential.

Engineered with full-metal construction and fan-less design, the MB601V4KW-B delivers PCIe Gen 4.0 transfer speeds up to 64Gb via a direct U.2 (SFF-8639) interface, making it well-suited for high-speed workflows such as AI model training, data logging, and industrial system caching. Drive-level security and protection are reinforced through a 2-segment keylock and EMI grounding, ensuring safe and stable operation in sensitive environments.

Protection Against Dust and Water Splashes
Designed with a rugged IPX6-rated water-resistant front cover, the MB601V4KW-B protects the internal drive from dust, moisture, and foreign objects, ensuring reliable operation in harsh industrial or field environments.

This makes it particularly suited for extreme deployment scenarios such as military drones, underwater robotics or compact submarines, and autonomous vehicle platforms, where the combination of environmental sealing and high-speed NVMe storage is critical for mission success.

Secure Locking Mechanism for Data Protection

The MB601V4KW-B features an Eagle-hook locking mechanism to prevent accidental SSD ejection and ensure secure drive retention during operation. For added security, it incorporates a 2-segment security keylock, which restricts access to authorized users and protects against physical drive theft or tampering.

These features make the MB601V4KW-B a choice for data-sensitive environments such as government systems, cybersecurity infrastructure, and financial institutions – where physical access control is as critical as digital encryption.

Quick SSD Swaps, Cleaner System

The full-metal removable drive tray of the MB601V4KW-B supports effortless ^(*) hot-swapping of U.2/U.3 NVMe SSDs, allowing for rapid replacement in time-sensitive environments such as field data collection, defense systems, and edge computing. It supports SSDs up to 15mm in height, offering flexibility across various enterprise-grade NVMe drives. Additionally, a spring-loaded anti-dust flap covers the drive slot when the tray is removed, keeping dust, debris, and foreign objects from entering the system. This helps maintain long-term reliability and internal cleanliness, even in rugged or outdoor deployments.
Note: Hot-swap support is dependent on the host system.

Built for Harsh Environments
The MB601V4KW-B is constructed entirely of metal, including the chassis, drive tray, and mounting hardware, making it compliant with flammability requirements and robust enough to withstand vibration, shock, and industrial usage.

As downward disconnection is one of the common issue that lead to damaging or even snapping the rear connector, the ToughArmor MB601V4KW-B comes with rear metal support brackets. The benefits to having the support brackets is to reduce the chances accidental damage to the rear connector when disconnecting improperly and prevent it from shifting around. This also serves as a guide when inserting or removing the SFF-8639 male-connector, making it useful when dealing with limited space.

Unlock the Power of PCIe 4.0 with U.2 SFF-8639

The MB601V4KW-B is engineered with the U.2 (SFF-8639) interface with support for PCIe 4.0, it delivers blazing-fast transfer speeds of up to 64Gb, enabling ultra-low latency and throughput for real-time data capture, large-scale simulation, and fast storage caching. Compared to SATA-based solutions, PCIe 4.0 offers over 10x the bandwidth, making it for modern, high-demand systems.

Clear Status Monitoring

An LED indicator on the front panel shows power and drive activity status. The built-in Active Power Technology (APT) ensures that the LED is only active when a drive is installed, conserving energy when the bay is empty.

Product Compatibility

The MB601V4KW-B is compatible with motherboards, RAID/HBA cards, and M.2 adapters from major brands including Adaptec, Areca, Broadcom, HighPoint, Supermicro, and more. This compatibility gives you the freedom to choose from a wide range of hardware options, moving beyond the constraints of single-brand system configurations.
