Encrypted desktop drive for regulated data

The iStorage diskAshur DT2 20TB Graphite is a 3.5-inch desktop external hard drive that uses a built-in keypad for PIN authentication before the volume becomes visible to the host. It targets organisations and individuals who must meet GDPR, HIPAA or CCPA requirements and need 20TB of capacity without installing management software.

Replaces unencrypted USB drives when compliance is

The jump from a standard portable drive is worth it when data loss would trigger regulatory penalties or contractual breach, because this unit delivers FIPS 140-2 Level 3 validation and AES-XTS 256-bit hardware encryption that engages the moment the drive is unplugged. Buyers who only need casual backups or who cannot accommodate a mains-powered 3.5-inch form factor will not benefit from the added cost and size.

Limited by USB 3.2 bandwidth

Real-world throughput tops out at 277MB/s read and 271MB/s write, which is the practical ceiling of the USB 3.2 interface combined with a conventional spinning disk. Workloads that demand sustained multi-gigabit speeds or sub-millisecond latency will hit this bottleneck regardless of the host system.

Questions about this item

What power connection does the 3.5" 20TB desktop drive require to operate?

The drive is a mains-powered desktop unit; plug the supplied power adapter into a wall outlet and connect the USB 3.2 cable to the host.

How do I set a personal PIN on the keypad before first use?

Press the unlock key, enter the factory default code shown in the quick-start guide, then follow the on-screen prompts to create a 7-15 digit PIN.

Is the internal 20TB drive user-replaceable if it fails after the warranty period?

The enclosure is tamper-sealed for FIPS 140-2 Level 3 compliance; opening it voids the certification, so the drive module is not designed for user replacement.
