Key specifications at a glance

Keep sensitive files behind a PIN

Enter your personal 7–15-digit PIN on the integrated keypad to unlock the drive. Hardware-based AES-XTS 256-bit encryption protects data in real time, so security does not depend on software running on the host device.

A dedicated secure microprocessor uses physical protection mechanisms to help defend against tampering and bypass attempts. If it detects an automated attack, the drive enters a frozen state. This makes the diskAshur PRO² a practical choice for confidential work files and backups.

Connect across supported systems

The drive is plug and play and uses a USB Type-A connection. It supports Windows, macOS, Linux, Android and server operating systems. Because setup and operation are software-free, you can use it across supported devices without installing a dedicated application.

USB 3.2 Gen 1 provides a maximum transfer rate of 5,000 Mbit/s. For file transfers, the stated read speed is 171 MB/s and write speed is 148 MB/s.

A portable build for regular use

The black aluminium housing weighs 325g and measures 124 × 84 × 27mm. It is dust resistant, water resistant and wear resistant, which helps when you carry it between work locations. LED indicators provide status information during use.
