The iStorage datAshur PRO 128 GB is a hardware-encrypted USB flash drive offering FIPS-Level 3 security and a rugged aluminum chassis with IP68 protection.

Products in the top-left offer the best value (high score, low price).

Industry retailers and datasheets position the datAshur PRO as a high-security, rugged solution for regulated environments, stressing its FIPS-level encryption, durability certifications, and fast USB 3.2 performance, while noting the lack of independent editorial reviews.

Professional reviewers and editors are not directly quoted in the available sources; the product is presented primarily through manufacturer claims emphasizing FIPS 140‑2 Level 3 compliance, TAA compliance, and the AegisWare firmware’s malware resistance.


No consumer reviews or ratings were found in the research, so everyday user sentiment cannot be determined from the available data.
