Secure portable storage for regulated data

The iStorage diskAshur PRO2 is a 3TB portable hard drive built around a hardware-encrypted, PIN-authenticated design. It targets professionals and organisations that must meet FIPS 140-2 Level 3 and Common Criteria EAL4+ requirements without installing host software. The integrated USB 3.1 cable works with Windows, macOS, Linux, Android, Chrome OS and thin-client platforms.

Thermals noise and power in daily use

The 2.5-inch drive draws power solely from the USB port, so no external adapter is needed. Its IP56-rated enclosure resists dust and water jets while the epoxy-sealed internals add tamper evidence. In typical office environments the unit runs silently with no active cooling, and the graphite chassis stays cool during normal file transfers.

Behaviour under sustained load

Sequential reads reach 361 MB/s and writes 358 MB/s over USB 3.2, maintaining those rates across large data sets. After 15 consecutive failed PIN attempts the encryption key is destroyed and the drive locks, a brute-force defence that activates under any workload. The drive can then be reset to factory defaults and redeployed.

Questions about this item

How do I set up the iStorage IS-DAP2-256-3000-C-X for the first time, and what is the step users often miss?

Connect the integrated USB 3.1 cable to any compatible device. Enter a new 7-15 digit PIN twice to create the Admin PIN. The step often missed is confirming the PIN a second time before the drive unlocks and becomes accessible.

What maintenance will the IP56-rated enclosure and epoxy-sealed internals require over time?

The IP56 certification protects against dust and water jets; wipe the graphite casing with a dry cloth if exposed to debris. The epoxy resin covering all components is permanent and requires no user maintenance, but physical damage to this layer voids tamper evidence.

At what point does the brute-force defence activate and erase the encryption key?

After 15 consecutive incorrect PIN entries, the drive assumes an attack, deletes the AES 256-bit XTS encryption key, and locks permanently. Data is lost, but the drive can be reset to factory defaults and redeployed with a new Admin PIN.
