ICY DOCK TOUGHARMOR EX MB491V5K-B 2.5 U.2/U.3 NVME SSD PCIE 5.0 MOBILE

The ICY DOCK ToughArmor EX MB491V5K-B is a robust U.2/U.3 NVMe SSD mobile rack enclosure designed specifically for mission-critical military, industrial, and in-vehicle computing systems. Constructed with heavy-duty full-metal housing, the MB491V5K-B is inherently compliant with flammability requirements and offers superior durability under extreme conditions. Its removable drive tray with metal barrel keylock and thumbscrew secures the SSD in place, preventing unauthorized access and protecting the drive against shock, vibration, and accidental ejection during transit.

With support for PCIe 5.0 and up to 128Gbps transfer speeds, the MB491V5K-B delivers the bandwidth needed for real-time analytics, aerospace data logging, AI model training, and other high-performance applications.

Secure & Rugged Removable NVMe SSD Design

The hot-swappable drive tray supports up to 15mm U.2/U.3 NVMe SSDs and allows for seamless SSD replacement and maintenance-no need to open the system chassis. This makes it an ideal solution for data shuttle/sneakernet workflows, edge deployments, or mobile systems where uptime and security are paramount.

Dual-Layer Security for Critical Environments

To ensure maximum protection, the MB491V5K-B integrates a dual-lock mechanism. The metal barrel keylock prevents unauthorized physical access, while the thumbscrew lock keeps the drive tray firmly in place, reducing vibration and risk of disconnection caused by motion or impact.

This double-lock protection makes it an ideal fit for defense, law enforcement, autonomous vehicles, industrial robotics, or any edge-computing system where data integrity and drive retention must be secured even under physical duress.

Military-Grade Readiness

The MB491V5K-B is engineered with full-metal construction and designed to meet MIL-STD-810H Method 516.8 (Shock) and 514.8 (Vibration) standards. The enclosure is MIL-STD-ready and built to operate in demanding environments such as aerospace, field-deployed servers, and high-vibration settings like transportation or factory automation.

Thermal Optimization for PCIe 5.0 SSDs

High-speed NVMe SSDs, especially those operating on PCIe Gen 5.0, generate significant heat under full load. To combat this, the MB491V5K-B features an integrated high-performance 25mm x 25mm cooling fan, precision-cut ventilation holes on the front panel, and thermally optimized PCB cutouts for improved airflow.

Combined with its all-metal body that acts as a heat sink, this active and passive hybrid cooling system ensures your SSD operates at peak performance with improved thermal longevity and system stability.

Intelligent Drive Activity Monitoring

The MB491V5K-B includes a smart LED indicator system that displays drive power and activity status. Leveraging ICY DOCK's Active Power Technology (APT), the LED only illuminates when a drive is inserted, helping to conserve system power while maintaining visibility during operation.
