Icy Dock has unveiled its ToughArmor EX MB491V5K-B, a U.2/U.3 NVMe SSD mobile rack enclosure built for military, industrial, and in-vehicle computing. The unit features a full-metal housing designed for extreme durability, a dual-lock security system with a metal keylock and thumbscrew, and support for PCIe 5.0 with up to 128 Gbps transfer speeds.

This enclosure is engineered to meet MIL-STD-810H shock and vibration standards, making it suitable for aerospace data logging and autonomous systems. Its hot-swappable tray allows for tool-free maintenance, while an integrated fan and optimized airflow manage the heat from high-speed Gen 5 drives. The design prioritizes data integrity and drive retention in high-motion environments.

The launch addresses a growing need for ruggedized storage in edge computing and defense applications, where standard consumer gear fails. As PCIe 5.0 adoption increases in high-performance sectors, reliable, secure, and removable drive solutions become critical for field operations and data shuttle workflows. Icy Dock backs the unit with a 5-year warranty.
