iStorage diskAshur DT3 4TB Secure Encrypted External Hard Drive - FIPS 140-3 Level 3 Certified with 256-bit Encryption

Product Overview

The iStorage diskAshur DT3 4TB Secure Encrypted External Hard Drive is a high‑capacity, enterprise‑grade storage solution designed for users who demand uncompromising data protection and regulatory compliance. With a generous 4 terabytes (TB) of raw storage, it delivers ample space for backups, media libraries, or large project files while maintaining the highest security standards.

Security Architecture

This drive is built around the FIPS 140-3 Level 3 Certified hardware encryption engine. FIPS (Federal Information Processing Standards) certification ensures that the device meets stringent government‑grade requirements for cryptographic modules. Level 3 certification indicates robust physical tamper resistance, secure key storage, and rigorous authentication mechanisms.

The disk employs 256‑bit AES-XTS encryption, a symmetric block cipher that provides strong confidentiality even against advanced adversaries. The XTS mode is specifically designed for storage devices, offering sector‑level encryption that protects data integrity while allowing efficient random access.

Hardware and Performance

The internal spinning platter operates at 7200 RPM, delivering consistent read/write speeds suitable for both everyday use and demanding workloads. Coupled with a dedicated USB 3.2 Gen 1x1 (USB‑C) interface, the drive achieves theoretical transfer rates up to 5 Gbps. This bandwidth is sufficient for rapid backups, large file transfers, and streaming high‑definition media.

The enclosure features a robust aluminum chassis that dissipates heat and protects against physical shock. The design also incorporates a built‑in fan‑less cooling system, ensuring quiet operation even under sustained load.

Authentication and Access Control

Access to the drive is protected by a PIN‑based authentication system. Users must enter a personal identification number before any data can be accessed or transferred. This mechanism prevents unauthorized use if the device falls into the wrong hands.

The PIN is stored in a secure, tamper‑resistant memory module that cannot be read or extracted by conventional means. Even if an attacker obtains the physical drive, they would still need to know the correct PIN to decrypt the contents.

Compliance and Certifications

• FIPS 140-3 Level 3 Certified: Meets U.S. federal standards for cryptographic modules.
• Common Criteria EAL5+: Provides assurance that the device has undergone rigorous security evaluation.
• TAA (Trade Agreements Act) Compliant: Suitable for use in defense and government environments.
• GDPR‑Compliant: Designed to meet European data protection regulations, ensuring privacy of personal data stored on the drive.

Operating System Compatibility

The disk is OS & Platform Independent. It presents itself as a standard mass storage device when connected via USB‑C, allowing seamless use with Windows, macOS, Linux, and other operating systems without the need for proprietary drivers.

Use Cases

Enterprise Backup: Securely archive critical business data with guaranteed encryption and tamper resistance.

Regulatory Compliance: Store sensitive information that must meet FIPS, GDPR, or TAA requirements.

: Safeguard personal photos, videos, and documents against theft or loss.

: Handle large video files while ensuring they remain confidential during transit.

Physical Design Features

• Black Aluminum Enclosure: Sleek, professional appearance with durable construction.
• USB‑C Connector: Reversible plug for easy connection on modern laptops and desktops.
• Compact Form Factor: Portable yet robust enough for desktop use.
• No External Power Requirement: Draws power solely from the USB interface, simplifying deployment.
