The ICY DOCK ToughArmor EX MB491V5K-B is a U.2 / U.3 NVMe SSD mobile rack specially designed for mission-critical military, industrial and automotive systems, which ensures reliable operation even in the most extreme environments. The all-metal, heavy-duty housing not only provides excellent mechanical protection, but also meets flammability requirements, making it an ideal choice for defense, industrial automation and embedded computing applications. The removable drive tray is equipped with a keyed cylinder lock and set screw that prevents unauthorized access and provides effective protection against shock, vibration and accidental loosening during transport or movement.

The mobile rack supports PCIe 5.0 and can provide data transfer speeds of up to 128 Gbps, making it fully suitable for tasks that require high bandwidth, such as real-time data processing, aeronautical data collection, artificial intelligence teaching or edge-computing systems. The drive tray with hot-swap design accepts U.2 or U.3 NVMe SSDs up to 15 mm high and enables fast drive replacement without disassembling the system case. This is especially beneficial for data exchange and "sneakernet" solutions, mobile systems or environments where minimizing downtime is of utmost importance.

The double security locking mechanism provides the highest level of physical protection. A solid metal key lock prevents unauthorized removal, while a locking screw holds the drive firmly in place, reducing the risk of connection errors due to vibration and impact. This design makes the device ideal for security systems, law enforcement applications, autonomous vehicles, industrial robotics and any environment where data security and stable drive mounting are essential requirements.

The all-metal design of the ToughArmor EX MB491V5K-B meets MIL-STD-810H 516.8 (Shock) and 514.8 (Vibration) standards, making it reliable for use in high-vibration, shock-prone or off-road environments. An integrated 25 × 25 mm active cooling fan, precisely designed front panel ventilation openings, and heat-optimized PCB cutouts ensure efficient management of the heat generated by high-performance PCIe Gen 5.0 NVMe SSDs. Together with the passive heat dissipation properties of the metal housing, these elements ensure optimal operating temperature, stable performance and long service life even under sustained load.

The built-in intelligent LED status indicator system provides clear feedback on the operation and activity of the drive. Thanks to the ICY DOCK Active Power Technology, the LED only lights up when a drive is inserted, thus reducing unnecessary energy consumption while maintaining easy control of the operating status. This sophisticated, industrial-grade solution is the perfect choice for any professional system where performance, security and reliability are not a matter of compromise.
