Secure Portable SSD with PIN Authentication

The iStorage diskAshur M2 is a 1TB external solid-state drive that uses a 7-15 digit PIN for hardware-based access control. It connects via USB 3.2 and requires no software installation to operate. The drive measures 45 by 12 by 111 millimetres and weighs 86 grams.

Suited for users needing certified physical security

This drive suits professionals who require FIPS 140-3 Level 3 validated encryption and IP68 dust and water resistance. It is not for buyers who want higher throughput than 370 MBps sequential speeds. It is also not for users who prefer software-based encryption or drives without a physical keypad.

AES-XTS 256-bit hardware encryption

The single specification that decides suitability is the integrated Common Criteria EAL 5+ certified secure microprocessor performing AES-XTS 256-bit encryption. This hardware engine meets FIPS PUB 197 standards and enables brute-force protection with independent Admin and User PINs.

Questions about this item

How do I set up the iStorage diskAshur M2 1TB and what is the common mistake during first use?

Connect the supplied USB Type A or Type C cable, then enter a 7-15 digit PIN to unlock. The common mistake is skipping Admin PIN creation, leaving no recovery path if the User PIN is forgotten.

What maintenance or replacement will the diskAshur M2 1TB need over time?

No scheduled maintenance is required. The sealed IP68 enclosure protects the 256-bit AES-XTS hardware encryption engine. Replace the drive only if physical damage exceeds the 4m drop or 2.7 ton crush ratings.

What performance limit appears first during sustained transfers on the diskAshur M2 1TB?

Sequential read and write speeds peak at 370 MBps over the USB 3.2 interface. Under sustained load the controller thermal throttle engages before the interface saturates, capping throughput at that 370 MBps ceiling.
