Secure 4TB portable drive

The iStorage diskAshur PRO2 provides 4TB of hardware-encrypted storage in a 2.5-inch graphite enclosure. A built-in keypad requires a 7-15 digit PIN before the drive becomes visible to the host. No software installation is needed, so it works on any device with a USB port including Windows, macOS, Linux, Android and embedded systems.

FIPS 140-2 Level 3 upgrade

This drive replaces standard portable hard drives when regulatory compliance or physical security is mandatory. It is certified to FIPS 140-2 Level 3 and uses a Common Criteria EAL5+ ready secure microprocessor with AES-XTS 256-bit encryption validated to FIPS PUB 197. The jump is worth it for organisations handling GDPR, HIPAA or CCPA data who cannot risk software-only encryption or unprotected media.

Sustained transfer and rugged use

Sequential reads reach 361 MB/s and writes 358 MB/s over the USB 3.2 Gen 1 interface, maintaining throughput during large backups. An IP56 rating protects against dust and water jets while the drive operates or rests in its carry case. After repeated incorrect PIN entries the drive enters a deadlock frozen state to thwart automated attacks. It is not for buyers who need solid-state speeds or capacities above 4TB.

Questions about this item

What physical space does the 2.5 inch 4TB drive need to fit?

The drive measures .79 inches high by 4.88 inches wide by 3.31 inches deep and weighs .50 lb, so it fits in a standard 2.5 inch drive bay or pocket.

How is the drive installed and what step do users often miss?

Connect the USB 3.1 cable to any USB port, then enter your 7-15 digit PIN on the built-in keypad to unlock; the drive will not mount until the PIN is entered.

What maintenance or replacement will the IS-DAP2-256-4000-C-X need later?

No scheduled maintenance is required; the IP56 rated enclosure resists dust and water, and the AES 256-bit hardware encryption module has no user-serviceable parts.
