Description

The most secure encrypted portable drive in the world.

Rocsecure EX31 is built on the latest FIPS Encryption engine and USB 3.1 Gen1 technology. When using Solid State Drives models connected to your host computer’s USB-C port, you will experience faster transfer speeds and performance which is unmatched to any other real-time encrypted drives in the market. EX31 include solid-state drives that are blazing fast, with up to a 4TB SSD. One of the most secure and cutting-edge hardware-based encryption chipsets is integrated into the internal circuitry of Rocsecure EX31 models. The chipset contains features such as Advanced Encryption Standard Algorithm AES-256 bit key strength, and real-time encryption so that there is virtually zero time in encrypting and decrypting the data. The encryption engine bears certifications from the National Institute of Standards and Technology (NIST), and FIPS Level 2 for a Cryptographic Module. Rocstor CryptoKey™ token key securely and easily exchanges stream encryption keys for use with the Rocsecure EX31 encryption/decryption engine and manages a confidential communications channel. The CryptoKey Token Key features a wide array of defense mechanisms specifically designed to prevent physical attacks on the device itself or logical attacks on the data transmitted between the token key and Rocsecure EX31 storage device. The Ruggedized Portable Enclosure aluminum design helps to protect your hard drive and data. The safety-centric mechanical design of Rocsecure EX31 series 2.5″ enclosures provides critical hardware protection features, including:

Secure Shock-Absorbent Mechanism

The full-length bridgeboard provides additional protection by supporting the entire length of the hard drive. A strong aluminum rim holds the hard drive chassis firmly in place, eliminating stress on the bridgeboard and preventing damage due to impact or violent movement.

Shock-Absorbent Protection

The shock-absorbent dampers strip between the bridgeboard and chassis offers additional resistance against accidental drops and bumps. The disposition of the hard drive and housing profile form an anti-shock chamber to cushion the blow of potential impacts.

Thermal Protection and Load-Bearing Case

The precision density of the rugged aluminum aircraft-grade border provides excellent heat dissipation and is strong enough to bear external weight. Rocsecure EX31 employs data encryption and pre-boot authentication allowing organizations to better protect and control access to their corporate and customer records, thus complying with regulations such as Sarbanes-Oxley (SOX), Health Insurance Portability and Accountability Act (HIPAA), and Gramm-Leach-Bliley (GLB); it is also FCC, CE compliant. A unique feature of the EX31 is that it requires a secure token key allowing you to insert the key directly onto the drive. This ensures protection from key-loggers who may be recording your keystrokes on other competitor drives with an integrated keypad on the drive. Together with full-disk encryption and token key based authentication, these features give you the ultimate level of protection with an unrivaled ease of use.

Unbreakable Security, Redefined for a New Era

The Rocsecure EX31 stands at the pinnacle of encrypted storage—built on a next-generation FIPS 140-2 Level 2 certified encryption engine and engineered for organizations that demand uncompromising protection of sensitive data. Every file is secured the instant it’s created with real-time AES-256 full-disk hardware encryption, powered by a NIST-validated cryptographic module designed to eliminate lag and eliminate software vulnerabilities. Whether you choose high-performance SSD capacities up to 4TB or traditional HDD options, the EX31 delivers blazing USB 3.1 Gen1 speeds and seamless USB-C connectivity, creating the fastest, most secure portable drive in its class.

A Smarter Way to Authenticate

At the heart of EX31 is the Rocstor CryptoKey™ — a secure hardware token that replaces vulnerable keypad PINs and eliminates exposure to key-loggers, shoulder-surfing, or remote credential theft. This cryptographic key establishes a confidential, tamper-resistant channel with the EX31 chipset using HMAC SHA-256 authentication, ensuring that only authorized users can unlock the drive. For environments requiring elevated security, EX31 supports both single-token authentication and two-factor authentication with additional password entry. No drivers, no software, and no OS dependencies—the EX31 operates flawlessly across Windows®, macOS®, Linux®, and any system that supports USB mass storage.

Engineered for the Unexpected

Precision-milled from rugged aluminum, the EX31 is built to survive real-world terrain—absorbing shock, dissipating thermal buildup, and protecting your data from sudden impact. A secure shock-absorbing mechanism suspends the drive inside an internal chamber, while a full-length bridgeboard and dampened shell minimize stress from drops, vibration, and movement. With optional MIL-standard waterproof and dust-resistant cases, the EX31 is ready for fieldwork, travel, and mission-critical operations where failure is not an option.

Compliance-Ready Confidence

From healthcare to finance, government to enterprise, the EX31 gives organizations a powerful tool for meeting strict data protection requirements. With full-disk hardware encryption and pre-boot authentication, it helps businesses meet HIPAA, SOX, and GLBA standards while maintaining corporate and customer trust. FCC and CE compliance ensures dependable performance, while Rocstor’s 2-Year Limited Warranty and lifetime free technical support provide long-term reassurance backed by American engineering.
