Secure portable SSD with PIN authentication

The iStorage diskAshur2 SSD provides 512GB of encrypted storage in a 2.5 inch form factor. Access is granted by entering a 7-15 digit PIN on the built-in keypad before the drive becomes visible to the host. No software installation is required, so the drive works on any device with a USB port across Windows, macOS, Linux, Android, Chrome, thin clients and embedded systems.

Sustained transfer rates and hardware protection

Sequential reads reach up to 361MB/s and writes up to 358MB/s over the USB 3.2 interface, maintaining those speeds for large file transfers rather than short bursts. All data is encrypted in real time by an on-board AES-XTS 256-bit engine validated to FIPS PUB 197, while the Common Criteria EAL4+ ready microprocessor locks the drive into a deadlock frozen state after repeated failed attempts. The IP56 rated enclosure resists dust and water splashes during daily transport.

Upgrade from unencrypted portable drives

This drive replaces standard external SSDs or hard drives that rely on software encryption or no encryption at all. The jump is worthwhile when regulatory compliance such as GDPR, HIPAA or CCPA requires hardware-based full-disk protection and a tamper-resistant design. It is not suited for workflows that demand higher throughput than the USB 3.2 interface can deliver or for users who need capacities beyond 512GB.

Questions about this item

Does the drive get noisy or hot when it runs continuously at 361 MB/s read speeds?

The solid-state design has no moving parts, so it stays silent and generates minimal heat even during sustained transfers at the rated 361 MB/s read and 358 MB/s write speeds.

What must my computer already have to use the keypad and encryption on this 512 GB model?

Only a standard USB port — the drive draws power from the bus and handles PIN entry and AES 256-bit hardware encryption entirely on board, with no software or drivers required.

Will this USB 3.2 drive work at full speed on my older laptop that only has USB 3.1 ports?

Yes, the interface is backwards compatible; it will operate at USB 3.1 speeds on older ports while still providing hardware encryption and keypad authentication.
