Hardware Data Destruction Systems: From Samurai USB Drives to Server Modules
Russian company GuardDo develops devices for instant physical destruction of data on storage media. The Samurai lineup has evolved from secure USB drives with self-destruct features to integrated modules for servers and laptops. These systems ensure compliance with Russia's Federal Law 152-FZ on personal data, which requires irreversible disposal of personal data without needing FSB or FSTEC licenses.
The technologies meet NIST SP 800-88 Rev.1 (Destroy level): for SSDs, they shatter NAND chips and controllers; for HDDs, they use degaussing plus PCB burnout. Independent R.LAB tests confirm data cannot be recovered even in lab conditions.
GuardDo Product Evolution
Development kicked off in 2008 with a "Rantech" patent for portable drives that format after six wrong password attempts. In 2011, the Samurai 24 brand launched, refined based on user feedback. By 2013, PC destructors were added, and mid-2010s brought Samurai HS (a 2U module for 9 drives), which lagged in performance and needed physical disk access.
HS production stopped, but similar units like Detector Systems' "Impulse-9V" are still made. In 2023, GuardDo refreshed the lineup at customer request:
- Samurai GX for servers.
- Samurai NT for laptops.
- Samurai PC for desktops.
- Plus: anonymous phones and drive disposers.
Samurai GX Technical Specs
The GX model is a 1U rack unit that connects directly to drives via adapters. It doesn't impact server performance: drives stay operational, and the server never goes down.
Destruction Methods:
- SSD: Silicon cracks, chip fragmentation, controller destruction.
- HDD: Degaussing + thermal PCB damage.
Activation: Button, mobile app, or security system integration. Wipe time: 4 seconds for a 4TB server. Tests: 0% recovery after 30 minutes, 24 hours, and one week.
| Model | Device Type | Key Features | Price (RUB) |
|--------|-------------|--------------|-------------|
| GX | Servers | Alarm integration, physical wipe | 75,000 |
| NT | Laptops | Hidden button, remote activation | 81,000 |
| PC | Desktops | Timers, relays | 70,200 |
Samurai NT: Stealth Destruction for Laptops
This 1×1.5 cm block fits inside laptops (non-Apple). Custom buttons: size, depth, even toothpick activation. NDAs keep installation looks under wraps.
Scenarios:
- Physical button.
- SMS/call.
- Triggers (timer, geolocation).
Test: 2 seconds on SSD, data unrecoverable by magnetic methods. Ideal for field workers handling top-secret info.
Standards Compliance and Use Cases
These systems aren't classified as secure cryptographic tools—just need a commission report describing the method. Clients: data centers, banks, state corporations, international firms. No reported failures or data recoveries.
Key Benefits:
- NIST SP 800-88 Rev.1 ensures Destroy-level security without performance hits.
- Zero-downtime integration: direct drive connections.
- Custom fit: buttons, activation scenarios.
- R.LAB tests: 100% irrecoverability for GX, NT, PC.
- 152-FZ compliance, no extra certifications needed.
Building these requires expertise in magnetic recording, silicon physics, and hardware design. Check NIST 800-88 and HDD residual layer studies.
