The essentials at a glance

Control access with your own PIN

Enter a personal 7–15-digit PIN on the integrated keypad to unlock the drive. A dedicated secure microprocessor helps defend against tampering and bypass attacks. If it detects an automated attack, the drive enters a frozen state.

The PIN-secured design works without software installation. This makes the drive practical across supported Windows, Mac, Linux, Android and server systems.

Keep large files close at hand

With 4TB of capacity, you can carry substantial archives, project files and backups in one portable drive. USB 3.2 Gen 1 offers a maximum transfer rate of 5000 Mbit/s. The drive is also plug and play for straightforward connection.

The 2.5-inch hard drive runs at 5400 RPM, with stated read speeds up to 171 MB/s and write speeds up to 148 MB/s. Actual transfer times depend on the files and connected system.

Built for mobile working

The aluminium housing is dust, water and wear resistant. These protections help guard the drive during everyday handling, but they do not make it waterproof. A cable lock slot provides an option for securing the drive at a workstation.

Certification credentials include NCSC CPA, FIPS 140-2 Level 2, NLNCSA BSPA and NATO Restricted. The drive also has LED indicators and a lock-out function.
