The DataLocker H300 (IronKey) is a hardware-encrypted external hard drive designed for secure portable storage of sensitive data. It uses FIPS 140-2 Level 3 validated hardware encryption (AES 256-bit in XTS mode) to protect data at rest. The drive features an onboard keypad for PIN-based authentication, eliminating the need for software or drivers on the host system. It is designed to be OS-agnostic and compatible with any USB-enabled host. The H300 is managed through DataLocker's SafeConsole platform, which enables centralized remote management of the device, including policy enforcement, device auditing, password resets, and remote wipe capabilities. This makes it suitable for enterprise deployments where administrators need visibility and control over portable storage devices. The device includes brute-force protection that wipes data after a configurable number of failed PIN attempts. It is ruggedized with IP67-rated dust and water resistance and meets MIL-STD-810F standards for durability. Key use cases include secure transport of sensitive files, compliance with data protection regulations (e.g., HIPAA, GDPR, NIST), and enterprise-controlled portable storage management. The drive is available in capacities ranging from 500GB to 2TB and connects via USB 3.0 for data transfer.
