Secure desktop storage

The iStorage diskAshur DT2 is a 4 TB desktop external hard drive that protects data with a hardware-based AES-XTS 256-bit encryption engine and an on-device keypad. It connects via USB 3.2 and requires no software installation, so it works the moment you plug it into any host with a USB port.

Compliance-focused users

Organisations that must meet FIPS 140-2 Level 3, Common Criteria EAL5+ or GDPR requirements will find the certified microprocessor and tamper-evident design aligned with those mandates. Buyers who need a drive powered solely by the USB bus or who want a smaller form factor for mobile use should consider a portable model instead.

Keypad authentication

The built-in keypad lets you set a 7-15 digit PIN that unlocks the drive before the operating system sees it, removing the need for software utilities or driver updates. Brute-force protection triggers a deadlock freeze after repeated failed attempts, and the drive remains fully functional across Windows, macOS, Linux, Chrome, Android and embedded platforms.

Perguntas sobre este artigo

What type of USB port must my computer have to power and connect this 3.5" desktop drive?

The drive uses a USB 3.1 interface and requires an available USB port on the host device; it draws power from an included external power adapter rather than the USB bus.

Will the hardware keypad and AES 256-bit encryption function if I plug the drive into an older USB 2.0 port?

Yes, the drive is backwards compatible with USB 2.0 ports; the onboard keypad and real-time hardware encryption operate independently of the USB version, though transfer speeds will be limited to USB 2.0 rates.

How can I verify the drive is encrypting data correctly after I set my 7-15 digit PIN?

After entering your PIN, the drive unlocks and appears as a standard volume; you can confirm encryption is active by disconnecting the drive — data becomes inaccessible until the correct PIN is entered again.
